BACKGROUND Subtypes of melanoma, such as mucosal, uveal, and acral, are believed to result in worse prognoses than nonacral cutaneous melanoma. After a diagnosis of distant metastatic disease, however, the overall survival of patients with mucosal, uveal, acral, nonacral cutaneous, and unknown primary melanoma has not been directly compared. MATERIALS AND METHODS We conducted a single-center,...

The etiology and pathogenesis of lentiginous acral melanomas are poorly understood. Recent studies have postulated that DNA repair mechanisms and cell growth pathways are involved in the development of melanoma, particularly changes in the MAPK pathways (RAS, BRAF, MEK 1/2, and ERK 1/2). The aim of this study is to assess the status of the MAP kinase pathways in the pathogenesis of acral melano...

A 5 year old girl with thoracic empyema developed a scarlatiniform rash and acral desquamation. Cultures from blood, throat, and pleural fluid all grew Streptococcus pyogenes, a common etiologic agent of pediatric thoracic empyema. The presence of a scarlatiniform rash and acral desquamation in children with a thoracic empyema may help identify the causative organism.

Superficial acral fibromyxoma are rare soft tissue tumors predominantly involving hands and feet of adults. There are only a few reported cases of this benign neoplasm, but no FNAC diagnosis of this tumor is reported in the literature. A Forty-eight year old female presented with a 5 x 3.5 cm globular, firm swelling over the right fifth toe. Fine needle aspiration cytology (FNAC) of the lesion...

Acral melanoma is commonly diagnosed in people of color and has worse prognosis than cutaneous melanoma, even when controlling for tumor stage. Here, we seek to assess differences mutational profiles acral melanomas, which could potentially impact treatment outcomes. Mutational 1273 patients (118 1155 cutaneous) from the American Association Cancer Research Project Genomics Evidence Neoplasia I...
