Delayed Diagnosis Of Klippel-Trénaunay Syndrome In A 23-Year-Old African American Male, Daniel A. Nguyen, Pranav Patel, Stephen E. Weis 2022 Medical City Fort Worth

Delayed Diagnosis Of Klippel-Trénaunay Syndrome In A 23-Year-Old African American Male, Daniel A. Nguyen, Pranav Patel, Stephen E. Weis

HCA Healthcare Journal of Medicine

Klippel-Trénaunay syndrome is a rare genetic disorder that typically presents as a triad of symptoms consisting of venous malformations (varicosities), capillary malformations (port-wine stain), and limb overgrowth. We followed a 23-year-old African American male with a past medical history of peripheral vascular disease, who was visiting the dermatology clinic for a persistent skin lesion on his thigh. During physical examinations, we noted a subtle port-wine stain on his right leg, right leg hypertrophy, and peripheral vascular disease. Skin findings were difficult to observe on his darker skin tone, Fitzpatrick skin type VI, which may have led to the delayed diagnosis ...


Presentations Of Cutaneous Disease In Various Skin Pigmentations: Cutaneous Abscesses, Christopher M. Wong, Christian J. Scheufele, Sandhya Bodapati, Daniel A. Nguyen, Ashleigh E. Hermann, Jean Elizze M. Charles, Michael Carletti, Stephen E. Weis 2022 Medical City Fort Worth

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Cutaneous Abscesses, Christopher M. Wong, Christian J. Scheufele, Sandhya Bodapati, Daniel A. Nguyen, Ashleigh E. Hermann, Jean Elizze M. Charles, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Cutaneous abscesses are collections of pus resulting from skin and soft tissue bacterial infections. They clinically exhibit the four cardinal inflammatory signs of pain, warmth, swelling, and erythema. In patients with darkly pigmented skin, classically-associated erythema may be challenging to appreciate and can lead to missed or delayed diagnosis. We compare abscess presentations in different skin types. Recognition of varying presentations of cutaneous abscesses in diverse skin colors will help clinicians utilize additional clues to identify and diagnose this entity correctly.


Presentations Of Cutaneous Disease In Various Skin Pigmentations: Inverse Psoriasis, Daniel A. Nguyen, Henry Lim, Christopher M. Wong, Christian J. Scheufele, Ashleigh E. Hermann, Jean Elizze M. Charles, Michael Carletti, Stephen E. Weis 2022 Medical City Fort Worth

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Inverse Psoriasis, Daniel A. Nguyen, Henry Lim, Christopher M. Wong, Christian J. Scheufele, Ashleigh E. Hermann, Jean Elizze M. Charles, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Inverse psoriasis is a clinical variant of psoriasis involving flexural or intertriginous areas of the body. Inverse psoriasis may be present in 3 to 36% of psoriasis patients. Lesions are clinically characterized as smooth, well-demarcated, erythematous plaques (raised, >1 cm) without the typical silvery scales of classic psoriasis. Differential diagnosis includes tinea infection, candidiasis, seborrheic dermatitis, or bacterial streptococcal infection. The clinical images in this review focus on identifying inverse psoriasis along the full spectrum of skin tones.

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Plaque Psoriasis, Ashleigh E. Hermann, Daniel A. Nguyen, Christopher M. Wong, Christian J. Scheufele, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Recent studies estimate that more than 8 million Americans have psoriasis. The prevalence of psoriasis in African Americans is 1.5% compared to 3.6% of Caucasians. Psoriasis is likely to be underdiagnosed among African Americans and other individuals with darker pigmented skin due to variations in clinical presentation in addition to disease distribution and severity. We present images of psoriasis vulgaris in a variety of Fitzpatrick skin types. Differences in the biology of skin pigmentation may explain the clinical masking of erythema in darker-skinned individuals. Recognition of this important difference will help clinicians utilize additional clues to identify and ...


Presentations Of Cutaneous Disease In Various Skin Pigmentations: An Introduction, Christian J. Scheufele, Delfin Weis, Stephen E. Weis 2022 University of North Texas Health Science Center at Fort Worth

Presentations Of Cutaneous Disease In Various Skin Pigmentations: An Introduction, Christian J. Scheufele, Delfin Weis, Stephen E. Weis

HCA Healthcare Journal of Medicine

Dermatological disease has historically been dependent on photography as a primary modality for education. Previously, photographs used for medical education were representative of the regional patient populations at that time; however, they have not proportionally reflected the rapidly changing demographics in the United States. Education on the diagnosis of cutaneous disease has, therefore, primarily relied on photographs of lighter skin tones. There is a need for a better representation of darker skin tones in dermatologic medical education. This article introduces a clinical series that highlights dermatological diseases in various skin pigmentations, which are commonly seen in the primary care office ...

Ets-Related Gene (Erg) Is Differentially Expressed In Dermatofibroma (Fibrous Histiocytoma) As Compared With Dermatofibromasarcoma Protuberans And Hypertrophic Scars: A Pilot Immunohistochemical Study, Meredith Hengy, Jesse Veenstra, Kyle Perry, David M. Ozog, Ben Friedman

Medical Student Research Symposium

Immunohistochemical staining can be of great utility in differentiating various cutaneous spindle cell neoplasms, particularly when the histomorphological appearance of the lesions is inconclusive. Nuclear staining for ETS-related gene (ERG), a highly sensitive endothelial cell marker, has seldom been studied in the context of cutaneous spindle cell neoplasms. Little is known about its specificity for vascular differentiation. In this pilot study, immunohistochemical analysis for ERG was performed on fifteen dermatofibromas (DF), ten keloids, and nine dermatofibrosarcoma protuberans tumors (DFSP). Consistent nuclear expression of ERG was found in DF [100% (15/15) of the lesions demonstrated >50% labeling of tumor cells ...

HCA Healthcare Journal of Medicine

Alopecia of the scalp has various causes and presentations. However, linear alopecia is unusual and lupus erythematosus presenting as linear alopecia is exceedingly rare. To date, there have been 16 documented cases of linear alopecia diagnosed as chronic cutaneous lupus erythematosus occurring in a linear configuration following Blaschko's lines. We report 2 additional cases and review the clinical and histologic features along with treatment. This Blaschkoid linear variant of cutaneous lupus erythematosus has distinct clinical and histologic characteristics that set it apart from other causes of alopecia and from classic forms of cutaneous lupus. These distinct features include a ...
