Blaschko-Linear Lupus Erythematosus In A Pediatric Patient, Marshall Hall, Olivia Mayer, Henry Lim, Dustin V. Wilkes, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

The lines of Blaschko represent epithelial cell migration during embryonic development. Rare forms of cutaneous lupus erythematosus may manifest along these lines, and lesions are termed Blaschko-linear lupus erythematosus (BLE). The purpose of this case study is to present a rare manifestation of linear cutaneous lupus erythematosus following the lines of Blaschko in a pediatric patient. To date, there are very few reports of BLE. We present a 17-year-old female with a 2-month history of a mildly tender growing lesion along the right nasofacial sulcus. The patient denied lesions elsewhere and any systemic, joint, or mucosal symptoms. A biopsy of …

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Tinea Corporis, Braden Van Alfen, Navya Peddireddy, Marshall Hall, Henry Lim, Christian Scheufele, Garrett Furth, Dustin Wilkes, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Tinea corporis is a common superficial fungal infection caused by dermatophytes. It typically presents as well-defined, pruritic, annular papules and plaques with central hypopigmentation. The differential diagnosis includes pityriasis rosea, nummular dermatitis, plaque psoriasis, tinea versicolor, granuloma annulare, and discoid lupus. This article compares different presentations of tinea corporis in various skin types as classified by the Fitzpatrick scale. Recognizing varying presentations of tinea in patients of different skin tones will aid in early and appropriate diagnosis and treatment.

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Keratosis Pilaris, Henry Lim, Reem Ayoub, Madelyn Richards, Marshall Hall, Christian Scheufele, Dustin Wilkes, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Keratosis pilaris (KP) is a common benign disorder involving hyperkeratosis of the skin. It is associated with other common dry skin disorders such as atopic dermatitis and ichthyosis vulgaris. Lesions are clinically characterized as symmetrically distributed, monomorphic, folliculocentric, hyperkeratotic papules with a variable degree of perifollicular erythema. The appearance can be likened to spikey bumps that are commonly located on the arms, legs, and buttocks. Awareness of KP is important as every primary care clinician will see patients with this disorder. Identification can support the diagnosis of other associated skin diseases. Education about KP and its treatment may alleviate psychological …


An Unusual Presentation Of Lichen Planus Pigmentosus Inversus Responsive To Topical Tacrolimus: A Case Report, Valeria J. Gonzalez-Molina, Sujitha Yadlapati, Michael R. Hohnadel, Rick Lin Dec 2025

An Unusual Presentation Of Lichen Planus Pigmentosus Inversus Responsive To Topical Tacrolimus: A Case Report, Valeria J. Gonzalez-Molina, Sujitha Yadlapati, Michael R. Hohnadel, Rick Lin

HCA Healthcare Journal of Medicine

Background

Lichen planus pigmentosus inversus (LPPI) is a rare variant of lichen planus pigmentosus (LPP), characterized by sharply defined violaceous-brown to gray macules, papules, patches, or plaques primarily affecting the intertriginous and flexural areas. Unlike LPP, which predominantly affects Fitzpatrick skin types III to IV in sun-exposed areas, LPPI spares these regions and has been predominantly reported in White and Asian patients.

Case Presentation

We discuss a 66-year-old man with Fitzpatrick skin type III who presented with a year-long history of mildly itchy, hyperpigmented plaques on the inframammary folds. These plaques developed after being hospitalized for a chronic urinary tract …


Persistent Lichenoid Reaction And Eruptive Keratoacanthomas Following Pd-1 Inhibitor Therapy, Paul Vance, Michael Hohnadel Jun 2025

Persistent Lichenoid Reaction And Eruptive Keratoacanthomas Following Pd-1 Inhibitor Therapy, Paul Vance, Michael Hohnadel

HCA Healthcare Journal of Medicine

Background

Immune checkpoint inhibitors, such as nivolumab, have become integral in treating metastatic malignancies by enhancing immune responses against tumors. However, they are associated with immune-related adverse events (irAEs), including cutaneous reactions. We report a case of persistent lichenoid dermatitis during therapy and eruptive keratoacanthomas (KAs) following the cessation of nivolumab.

Case Presentation

A 77-year-old Caucasian man presented with a subcutaneous melanoma on the left lateral chest, treated with excision followed by adjuvant nivolumab. Seven weeks into therapy, he developed pruritic erythematous macules, forming patches on his forearms, later spreading to his trunk. Biopsy confirmed lichenoid dermatitis. Treatment with triamcinolone …


Apocrine Breast Cancer With Psammoma Bodies In A Male Patient, Alena Bashinskaya, Eric W. Baum, Michael B. Morgan Dec 2024

Apocrine Breast Cancer With Psammoma Bodies In A Male Patient, Alena Bashinskaya, Eric W. Baum, Michael B. Morgan

HCA Healthcare Journal of Medicine

Introduction

While male breast carcinoma is a relatively uncommon occurrence, its incidence is on the rise, potentially attributed to sporadic pathophysiological mechanisms, primarily involving hormonal imbalances. Invasive apocrine carcinoma represents a small fraction of global breast malignancies, with limited instances reported among male patients in the literature. The clinical presentation of an apocrine breast carcinoma closely resembles that of other breast cancer subtypes, as it is most often described as a solitary ulcerative nodular lesion occupying a retro-areolar region of the breast. Herein, we describe a novel case of an apocrine male breast carcinoma metastasizing to the skin, given that …


Actinic Granuloma Complicated By Secondary Syphilis: A Case Report, Kevin H. Nguyen, Christopher M. Wong, Ethan Q. Nguyen Apr 2024

Actinic Granuloma Complicated By Secondary Syphilis: A Case Report, Kevin H. Nguyen, Christopher M. Wong, Ethan Q. Nguyen

HCA Healthcare Journal of Medicine

Introduction

Actinic granuloma (AG) is a rare skin eruption thought to result from a sun-induced inflammatory response attracting giant cells, which are large, multinucleated, and inflammatory, to form granulomas and degrade surrounding elastic material. Clinically, lesions begin on sun-exposed skin as pink papules and nodules that coalesce into demarcated annular plaques with a hypopigmented center. Histologically, actinic elastosis surrounds the outer annulus ring, with histiocytes and giant cells within the raised border, and the innermost central zone is filled with minimal to absent elastic fibers.

Case Presentation

We present a middle-aged female with a pruritic eruption of diffuse erythematous macules …


Management Of Keloid-Associated Pruritus With Topical Crisaborole 2% Ointment: A Case Report, Daniel A. Nguyen, Elizabeth Thai Ms, Stephen E. Weis Apr 2024

Management Of Keloid-Associated Pruritus With Topical Crisaborole 2% Ointment: A Case Report, Daniel A. Nguyen, Elizabeth Thai Ms, Stephen E. Weis

HCA Healthcare Journal of Medicine

Introduction

The pathophysiology of keloid formation is poorly understood, and current treatments, including intralesional corticosteroids, cryotherapy, and surgery, are often associated with high resistance to treatment and recurrence. The multifactorial pathogenesis of keloid formation suggests that aberrant inflammatory cytokine signaling associated with keratinocyte dysregulation may contribute to keloid-associated pruritus.

Case Presentation

In this paper, we report 2 cases of keloid-associated pruritus that were successfully treated with topical crisaborole 2% ointment, a phosphodiesterase 4 (PDE4) inhibitor. Both patients had previously undergone multiple unsuccessful treatments before being treated with crisaborole 2% ointment. In both cases, the patients experienced complete relief of pruritus …


Presentations Of Cutaneous Disease In Various Skin Pigmentations: Porokeratosis, Henry Lim, Christopher M. Wong, Christian J. Scheufele, Daniel A. Nguyen, Michael Carletti, Stephen E. Weis Apr 2024

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Porokeratosis, Henry Lim, Christopher M. Wong, Christian J. Scheufele, Daniel A. Nguyen, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Porokeratosis was first described in 1893. It is a relatively rare disorder with over 9 subtypes. Lesions are clinically characterized as well-demarcated, erythematous papules (raised, <1 cm) or plaques (raised, >1 cm), with an atrophic center, and raised scaly border. Porokeratosis is an important diagnosis to identify because it may undergo malignant transformation and mimics many commonly encountered diagnoses. These commonly mimicked diagnoses include squamous cell carcinoma, tinea corporis, nummular dermatitis, and psoriasis vulgaris, to name a few. The clinical images in this review focus on identifying porokeratosis along the full spectrum of skin tones.

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Chronic Atopic Dermatitis, Cecilia Nguyen, Jordan Thompson, Daniel A. Nguyen, Christopher M. Wong, Christian J. Scheufele, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Atopic dermatitis is a chronic inflammatory skin disorder classically affecting flexural areas of the body. It is present in children and adults, including those with darker skin pigmentation. Chronic lesions are hyperpigmented plaques that are dry, cracked, and/or scaly often with lichenification. Differential diagnoses include psoriasis, seborrheic dermatitis, ichthyosis, and pityriasis rosea. This article will showcase clinical images with varying presentations of chronic atopic dermatitis in a range of age groups and skin colors according to the Fitzpatrick scale.


Presentations Of Cutaneous Disease In Various Skin Pigmentations: Seborrheic Dermatitis, Christian J. Scheufele, Christopher M. Wong, Daniel A. Nguyen Do, Pharmd, Michael Carletti, Stephen E. Weis Apr 2024

HCA Healthcare Journal of Medicine

Seborrheic dermatitis is a common dermatologic disease affecting patients of all ages, ethnicities, and skin pigmentations. The rash often affects the scalp, ears, and central face. The underlying skin pigmentation of the individual may affect how this disease presents. We present several cases of seborrheic dermatitis in individuals of varying ages, genders, and skin pigmentations.


Eruptive Sebaceous Hyperplasia: A Case Report And Review Of The Literature, Carsten Z. Steinmetz, Amanda Getz, Andras Schaffer, Stephen K. Richardson Aug 2023

Eruptive Sebaceous Hyperplasia: A Case Report And Review Of The Literature, Carsten Z. Steinmetz, Amanda Getz, Andras Schaffer, Stephen K. Richardson

HCA Healthcare Journal of Medicine

Introduction

Eruptive sebaceous hyperplasia (ESH) is a benign process characterized by the acute onset and rapid proliferation of sebaceous glands, typically on the face. Although historically attributed to cyclosporine therapy, the preponderance of reports over the past 2 decades suggests a more complex etiology. There is increasing thought a combination of multiple medications as well as a genetic component contribute to ESH’s clinical presentation. Despite these theories, the exact cause of ESH in immunosuppressive therapy is poorly understood.

Case Presentation

To our knowledge, we report the third case of ESH arising in multimodality immunosuppressive therapy, consisting of tacrolimus, mycophenolate mofetil, …

Resolved Peristomal Erosive Papulonodular Dermatitis Mimicking Nevoid Hyperkeratosis Of The Nipple And Areola, Christa M. Tomc, Daniel A. Nguyen, Joseph S. Susa, Stephen E. Weis

HCA Healthcare Journal of Medicine

Introduction

Nevoid hyperkeratosis of the nipple and areola (NHKNA) is a rare cutaneous entity with a distinct clinical and histological presentation. The type II form of this condition can result from various dermatoses, such as irritant contact dermatitis. Erosive papulonodular dermatitis is a chronic irritant dermatitis that often occurs in areas of occlusion and maceration, such as peristomal skin. Pseudoverrucous papules and nodules are a variant of erosive papulonodular dermatitis and have a non-specific histologic pattern of reactive hyperplasia.

Case Presentation

We present a case of a patient with resolved peristomal erosive papulonodular dermatitis who presented status-post ileostomy reversal with …

Clinical and histological changes supported the diagnosis of DRESS syndrome caused by intravenous (IV) ampicillin …


Congenital Giant Juvenile Xanthogranuloma, Let It Be, Michael Carletti, Daniel A. Nguyen, Joseph S. Susa, Stephen E. Weis Dec 2022

Congenital Giant Juvenile Xanthogranuloma, Let It Be, Michael Carletti, Daniel A. Nguyen, Joseph S. Susa, Stephen E. Weis

HCA Healthcare Journal of Medicine

Juvenile xanthogranuloma (JXG) is a rare type of non-Langerhans cell histiocytosis. JXGs are benign and have a self-limiting course generally lasting 6 months to 3 years, with some reported durations longer than 6 years. We present a rarer congenital giant variant, defined as lesions with a diameter larger than 2 cm. It is uncertain if the natural history of giant xanthogranulomas is similar to the usual JXG. We followed a 5-month-old patient with a 3.5 cm in diameter, histopathologically-confirmed, congenital, giant JXG located on the right side of her upper back. The patient was seen every 6 months for 2.5 …

Pleomorphic Dermal Sarcoma: A Clinical And Histopathologic Emulator Of Atypical Fibroxanthoma, But Different Biologic Behavior, Michael Carletti, Daniel A. Nguyen, Peter Malouf, Zachary Ingersoll, Gregory A. Hosler, Stephen E. Weis

HCA Healthcare Journal of Medicine

Pleomorphic dermal sarcoma (PDS) can clinically and histopathologically mimic atypical fibroxanthoma (AFX). However, it has a more aggressive clinical course with a higher recurrence rate and metastatic potential. This case presentation aims to report a rapidly-growing, exophytic, 4 cm tumor following a non-diagnostic shave biopsy 2 months prior and to highlight distinctive features between PDS and AFX needed to make the correct diagnosis. Like AFX, PDS occurs on the sun-damaged skin of the elderly, usually on the head and neck. Also, like AFX, PDS histopathologically consists of sheets or fascicles of epithelioid and/or spindle-shaped cells, often with multinucleation, pleomorphism, and …


Acyclovir-Resistant Anogenital Herpes Simplex Virus In An Hiv Patient With Pseudoepitheliomatous Hyperplasia Resembling Squamous Cell Carcinoma, Jean Elizze M. Charles, Stephen E. Weis, Gregory A. Hosler Aug 2022

Acyclovir-Resistant Anogenital Herpes Simplex Virus In An Hiv Patient With Pseudoepitheliomatous Hyperplasia Resembling Squamous Cell Carcinoma, Jean Elizze M. Charles, Stephen E. Weis, Gregory A. Hosler

HCA Healthcare Journal of Medicine

Background

Herpes simplex virus (HSV) is a common infection. However, it may present atypically when patients are immunocompromised, such as with slowly expanding, long-lasting ulcerative or hypertrophic lesions. The histopathologic finding of pseudoepitheliomatous hyperplasia (PEH) can occur in a variety of situations where there is chronic inflammation and can be seen in patients with chronic HSV. Atypical presentations of HSV, particularly hypertrophic lesions with histopathologic findings of PEH, can be misinterpreted as squamous cell carcinoma, create difficulty in diagnosis and hinder appropriate treatment.

Case Description

We report a case of a 59-year-old female with a past medical history of human …

Cutaneous Malignant Melanoma: A Synthesis On Updated Guidelines For The Primary Care Perspective, Seetha Venkateswaran, Nicholas D'Angelo

HCA Healthcare Journal of Medicine

Cutaneous malignant melanoma (CMM) is a condition wherein malignant cells form in the melanocytic cells. CMM is a potentially lethal form of skin cancer, commonly found in sun-exposed areas of the body. There are multiple risk factors for disease development, such as genetic mutation and UV radiation among others. Diagnosis and staging is important in determining disease morbidity and mortality. The United States Preventive Services Task Force (USPSTF) and the American Academy of Dermatology (AAD) have their respective guidelines and consensus on diagnosis, staging and treatment. It is imperative to delineate and educate primary care physicians on CMM, as they …
