Invasive penile squamous cell carcinoma.

Invasive penile squamous cell carcinoma (PSCC) is a rare malignancy with considerable morbidity and mortality. Because a delayed or incorrect diagnosis can have a devastating outcome, physicians should maintain a high index of clinical suspicion for PSCC in patients presenting with penile lesions, particularly in young or middle-aged patients in whom presentation of PSCC is uncommon. We report the case of a 27-year-old circumcised man who presented with invasive PSCC following a diagnosis of condyloma 8 years prior.

The use of Mohs micrographic surgery (MMS) for melanoma in situ (MIS) of the trunk and proximal extremities.

Background: Evaluation of the entire surgical margin results in high rates of complete excision, low local recurrence rates, and maximal tissue conservation. Although well recognized for melanoma of the head and neck, few studies have focused exclusively on the trunk and proximal extremities.

Objective: We sought to evaluate the efficacy of Mohs micrographic surgery for melanoma in situ (MIS) of the trunk and proximal extremities, and determine adequate excision margins for MIS when total margin evaluation is not used.

The Paramidline Forehead Flap: A Clinical and Microanatomic Study.

Background: The traditional paramedian forehead flap (FHF) is an axial flap based on the supratrochlear artery (STA). Doppler examination is often used to ensure inclusion of the STA within the flap. The authors hypothesized that a FHF pedicle design could be simplified to extend from the midline of the glabella to 1.

Nodular amyloidosis: clinical recognition of an unusual entity.

Nodular amyloidosis is a protein deposition disorder that is important to recognize in the clinical setting. Identification and differentiation from primary systemic amyloidosis, which has an identical cutaneous presentation, but serious systemic implications, is of particular significance. Our case report highlights two patients who presented with isolated involvement of the plantar surface and ungual phalanges, each with concomitant tinea pedis.

Bullosis diabeticorum associated with a prediabetic state.

Bullosis diabeticorum, or diabetic bullae, is a non-inflammatory blistering condition that is virtually diagnostic of diabetes. Diabetic bullae most often present as painless, tense, superficial bullae that occur in an acral distribution and commonly heal in 2-6 weeks without scarring, but complications such as secondary bacterial infection or hemorrhage may occur. The diagnosis of bullosis diabeticorum in a nondiabetic patient should prompt screening for diabetes.

Urticarial vasculitis: a unique presentation.

Urticarial vasculitis is a relatively rare diagnosis in a patient presenting with urticaria. The process is classically described as a generalized eruption, painful more so than pruritic, lasting longer than 24 hours. Two forms of urticarial vasculitis have been described: ahypocomplementemic form more commonly associated with systemic disease, and a normocomplementemic form that is generally limited to the skin.
