Metastatic Squamous Cell Carcinoma Presenting as Symptom of AIDS.

The development of metastatic cutaneous squamous cell carcinoma in an otherwise healthy and young individual should prompt physicians to investigate for an underlying cause of immunosuppression. The following case presents an individual who underwent Mohs surgery of a poorly differentiated squamous cell carcinoma. Four months following Mohs surgery, the patient presented with lymphadenopathy and new skin nodules.

Folliculocystic and Collagen Hamartoma: A Subset of Fibrous Cephalic Plaque.

Tuberous sclerosis complex is known to cause a variety of cutaneous hamartomas, most commonly hypomelanotic macules, angiofibromas, shagreen patches, and fibrous cephalic plaques. In recent years, a new cutaneous hamartoma that bears physical and histological resemblance to fibrous cephalic plaque has been proposed called folliculocystic and collagen hamartoma. The primary difference between the two diagnoses is the histologic presence of infundibular cysts in the latter.

Superficial Clear Cell Sarcoma (Melanoma of Soft Parts) of the Large toe in an 80-Year-Old Female With a Rare Cytogenetic Translocation.

We present a case of clear cell sarcoma (CCS) on the left large toe of an 80-year-old female. CCS, also known as "melanoma of soft parts," is a rare soft tissue neoplasm that exhibits melanocytic differentiation. Most cases occur on the distal extremities of young female adults.

Firm Cutaneous Nodule on the Dorsal Hand: A Case Report on Fibroblastic Rheumatism.

Fibroblastic rheumatism (FR) is a rare dermatoarthropathy of unknown etiology. It is characterized by the onset of firm cutaneous nodules in patients with rheumatologic symptoms such as arthralgias or symmetric polyarthritis. Clinicopathologic correlation is critical in establishing the diagnosis, as the clinical manifestations can resemble other fibrosing conditions.
