Skin cancer screening and melanoma detection: a life saved.

Rural America spans about two-thirds of the land that composes the United States. There are major health disparities in this population including a lack of screening, a shortage in education, and limited access to health care providers. These health disparities combined with a lack of health insurance led our patient to ignore the asymptomatic melanoma on her right foot for 10 years.

Cetuximab-induced crusted pustular eruption with patchy alopecia.

A 52-year-old man with recurrent metastatic rectal carcinoma being treated with cetuximab presented to the emergency department with a diffuse papulopustular eruption on the face, scalp, chest, and groin, accompanied by patchy alopecia of the scalp and facial hair.

Recurrent basal cell carcinoma with intracranial invasion: a case report and literature review.

Basal cell carcinoma (BCC) is the most common malignancy in humans. We present a man with a recurrent BCC of the scalp that presented as an intracranial tumor 18 years after original excision.

Recurrent paraneoplastic wells syndrome in a patient with metastatic renal cell cancer.

A 58-year-old man with a history of hyperlipidemia and hypertension presented to the dermatology clinic with a 3-month history of a sudden onset, progressively worsening pruritic eruption involving the torso and extremities. Prior treatment included azithromycin and oral and intramuscular steroids, without improvement. Laboratory results demonstrated a serum eosinophil count of 7x10(3)/uL (normal 0-4).

Primary scalp angiosarcoma with metastasis to the liver in an orthotopic liver transplant patient.

Angiosarcoma is a rare malignant neoplasm of vascular endothelial cells. A majority are primarily in the skin. Angiosarcoma of the head and neck is the most common form, but only constitutes 0.

Syringocystadenocarcinoma papilliferum: a rare tumor with a favorable prognosis.

Syringocystadenocarcinoma papilliferum (SCACP) is a rare adenexal carcinoma with only 21 cases reported in the literature. Most patients describe a long-standing mass with recent change, supporting the idea that SCACP arises from malignant transformation of pre-existing syringocystadenoma papilliferum (SCAP). Syringocystadenocarcinoma papilliferum is generally treated with wide surgical excision of the lesion and patients do exceeding well and require no systemic therapy.

A case of glyburide-induced leukocytoclastic vasculitis.

Introduction: Medication-induced leukocytoclastic vasculitis is a small-vessel vasculitis that most commonly manifests with palpable purpuric lesions on gravity dependent areas. Development of the vasculitis occurs within weeks after the initial administration of the medication, with clearance upon withdrawal of the medication. Glyburide, a sulfonylurea medication, is used to treat non-insulin dependent diabetes mellitus.

Preterm infant with a late presentation of blueberry muffin lesions secondary to recombinant erythropoietin.

Our patient is a 26-week-old preterm female infant delivered by caesarean section secondary to severe maternal preeclampsia who had been receiving subcutaneous recombinant erythropoietin (r-EPO) for anemia of prematurity. At 8 weeks of age after 8 doses of r-EPO, the infant developed numerous non-blanching erythematous macules and patches located on the back, posterior shoulder, and posterior arms, concerning for late-onset blueberry muffin lesions. Biopsy of the lesions confirmed dermal hematopoiesis.

Squamous cell carcinoma of the penis and topical combination corticosteroid products: a cautionary case.

Squamous cell carcinoma of the penis is fairly uncommon, but an important clinical entity with significant patient morbidity. Early diagnosis is important to allow for conservative management and to avoid aggressive surgical resection. We present a case of an invasive squamous cell carcinoma of the glans penis, which was treated with topical antifungals and corticosteroids for 2 years prior to diagnosis, necessitating partial glansectomy.

Locating the sural nerve during calcaneal (Achilles) tendon repair with confidence: a cadaveric study with clinical applications.

The sural nerve is at risk of iatrogenic injury even during minimally invasive operative procedures to repair the calcaneal (Achilles) tendon. Through 107 cadaveric leg dissections, the data derived from the present study was used to develop a regression equation that will enable surgeons to estimate the intersection point at which the sural nerve crosses the lateral border of the Achilles tendon, an important surgical landmark. In most cases, the sural nerve crossed the lateral border of the Achilles tendon 8 to 10 cm proximal to the superior border of the calcaneal tuberosity.

Oxalosis involving the skin: case report and literature review.

Background: The primary hyperoxalurias are a group of rare autosomal recessive metabolic disorders associated with abnormal overproduction of serum oxalate and subsequent deposition in tissue. Most patients present at an early age with recurrent urolithiasis and renal failure. Vascular deposition of oxalate-producing skin manifestations, such as livedo reticularis, acrocyanosis, peripheral gangrene, and ulcerations, is typical of the primary hyperoxalurias.
