Acral Lentiginous Melanoma: A Rare Variant With Unique Diagnostic Challenges, Taylor Gray, Brett Brazen, Maheera Farsi, Richard Miller

West Florida Division Virtual Research Day 2020

Acral lentiginous melanoma (ALM), named for its location and histological growth pattern, is a rare variant of melanoma. ALM presents on palms, soles, or in association with the nail unit.1 While ALM accounts for approximately 5% of melanomas diagnosed each year, it is the most commonly diagnosed subtype of melanoma in non-Caucasian patients.

Fracture blisters are tense vesicles or bullae that develop on edematous skin following some acute long bone fractures. Fracture blisters are infrequently seen, as the reported incidence is 2.9% to 6.6%.¹ This rare complication, may not regularly be encountered by Physicians in the hospital. Fracture blisters typically occur within 24-48 hours following high energy trauma injuries & may last up to several weeks. Ultimately, this condition can lead to prolonged hospital stay due to an increased risk of infection and delay in surgical intervention.² Early recognition of this dermatologic complication may be helpful in reducing hospital stays.

A Rare Case Of Primary Cutaneous Mucoepidermoid Carcinoma, Hassie Cooper, Maheera Farsi, Richard Miller, Pay Kamrani, Dudith Pierre Victor

West Florida Division Virtual Research Day 2020

Mucoepidermoid carcinoma (MEC) is a well-documented malignant tumor commonly found in the salivary glands. Cutaneous involvement is very rare, especially when presenting as a primary cutaneous neoplasm. Gallagher first described primary cutaneous MEC in 1959 and since then, to the best of our knowledge, there have been approximately 20 reports published in the literature. Here we present a very rare case of primary cutaneous mucoepidermoid carcinoma.

Hailey-Hailey Disease Successfully Treated With Low-Dose Naltrexone, John Moesch, Richard Miller

West Florida Division Virtual Research Day 2020

Hailey-Hailey disease (HHD) is an uncommon autosomal dominant disorder resulting from a mutation in the ATP2C1 gene resulting in dysfunction of the Golgi apparatus calcium-associated ATPase, thus interfering with intercellular calcium signaling.

HHD presents clinically as flaccid blisters and erosions in intertriginous areas, especially the axillae and groin.

The major histologic finding is acantholysis throughout the spinous layer of the epidermis, commonly referred to as a “dilapidated brick wall” appearance.

The initial lesions and associated symptoms usually develop during the second or third decade of life.

Complications of HHD include infections (bacterial, fungal, and viral), and malignant transformation (cutaneous squamous …

Malignant Degeneration Of Spiradenoma Of The Eyebrow, Christopher White, Kristin Witfill, Richard Miller

West Florida Division Virtual Research Day 2020

Spiradenocarcinoma is a malignancy of eccrine origin, with only 120 reported cases in the literature.¹ Elderly males and females are equally affected.² Benign spiradenomas along with their malignant counterpart are more frequent in patients with Brooke-Spiegler syndrome or familial eccrine spiradenoma, owing to the increased incidence of folliculosebaceous-apocrine tumors seen with these entities.³

Bilateral Sporotrichoid Cutaneous Atypical Mycobacterial Infection Due To Primary Inoculation, Erin Lowe, Alexa Broderick, Richard Miller

West Florida Division Virtual Research Day 2020

The group of mycobacterial species that excludes Mycobacteria tuberculosis and Mycobacteria leprae is known as nontuberculosis or atypical mycobacteria. Nearly all atypical mycobacteria species can cause cutaneous infection. The diagnosis is challenging as disease may take months to become clinically apparent, morphology is non-specific, routine culture has a low sensitivity, and organisms can be sparse on histopathologic examination. Antibiotic resistance and further complicates management. The Gulf Coast is the highest incidence region of cutaneous atypical mycobacterial infections. Here we present a challenging case of bilateral sporotrichoid atypical mycobacterial infection due to primary inoculation.

A Rare Case Of Trichilemmal Carcinoma: Histology And Management, Lisa F. Fronek, Allyson Brahs, Maheera Farsi, Richard Miller

West Florida Division Virtual Research Day 2020

Trichilemmal carcinoma (TC) is a rare, malignant, adnexal neoplasm that is derived from the outer root sheath (ORS) of the hair follicle. These tumors predominantly occur in elderly patients on sun-exposed areas, specifically on the head and neck with the face defined as the most common location. The mean age of diagnosis is 70 years old with a slight male predominance. These lesions are commonly identified as a papular, nodular, and sometimes, exophytic. They generally arise de-novo, but may also derivate from an underlying proliferating trichilemmal cyst with a loss of p53, a seborrheic keratosis, a nevus sebaceous, or a …
