Metastatic malignant melanoma and dermatomyositis: A paraneoplastic phenomenon.

Malignant melanoma has previously been reported with paraneoplastic syndromes including dermatomyositis. We report a case involving a 34-year-old woman who presented with a persistent skin rash over her neck and upper body, with clinical features suggestive of dermatomyositis. The patient had a history of a right shoulder lesion that was previously removed; a solitary axillary lymph node was detected on additional imaging and biopsy results were consistent with malignant melanoma.

Granulomatous mycosis fungoides with extensive chest wall involvement.

A 40-year-old woman presented with a 5-year history of a mass overlying her right pectoralis major muscle. Histopathology of the lesion revealed a florid granulomatous infiltrate including an atypical lymphocytic component with marked epidermotropism consistent with granulomatous mycosis fungoides. Staging investigations demonstrated the tumour to be localized to the right chest.

Successful treatment of in-transit melanoma metastases using topical 2-4 dinitrochlorobenzene.

A 78-year-old woman presented with multiple histologically proven in-transit melanoma metastases involving the lower half of the left leg. Initial therapy with liquid nitrogen cryotherapy had some short-lived success but was not tolerated by the patient. As further lesions began to develop, daily topical application of 2% 2-4 dinitrochlorobenzene to the lesions was commenced.
