We present a case of a superficial acral fibromyxoma (SAFM) of the distal aspect of the thumb with radiographic evidence of extrinsic pressure erosion of the underlying cortex. This 47-year-old woman presented with a slow-growing mass over the distal aspect of the right thumb that proved to be SAFM on surgical pathology. This is a relatively rare mesenchymal neoplasm of the periungual and subungual regions of fingers and toes.

Erythromelalgia, a rare cutaneous pain syndrome, is characterized by acral burning pain and flushing, often alleviated by cold and rest. Primary erythromelalgia is caused by gain-of-function mutations of genes encoding for sodium channels, resulting in hyperexcitability of pain signaling neurons. Autoimmunity and hematologic dyscrasias such as thrombocythemia have been implicated in secondary erythromelalgia.

Background: Acral lesions may represent the best/only skin lesions to biopsy in patients suspected to have dermatomyositis (DM). However, histopathologic features of acral DM skin lesions are poorly characterized.
Methods: We reviewed 50 acral biopsies from 46 DM patients and assessed numerous histopathologic features.

Introduction: The incidence of melanoma has been increasing in recent decades. BRAF mutations appear in 50%-70% of melanomas. The BRAF-targeted therapy increased the disease-free survival of patients with metastatic melanoma, but this response may be short, due to several resistance mechanisms, such as the presence of other subclones with mutations.
