Prostate carcinoma metastatic to the skin as an extrammamary Paget's disease.

Aim: The current paper describes a case of prostatic adenocarcinoma metastatic to the skin presenting as an extrammamary Paget's disease, a very rare and poorly characterised morphological entity. We report a case of prostatic carcinoma metastatic to skin showing a pattern of extramammary Paget's disease which has not been clearly illustrated in the literature Case presentation: A 63 year-old man with prostatic adenocarcinoma developed cutaneous metastases after 16 years. The inguinal metastases were sessile and 'keratotic.

Amyopathic dermatomyositis resembling stasis dermatitis.

This case describes an unusual presentation of dermatomyositis in a patient with ovarian carcinoma. The eruption appeared as a venous stasislike dermatitis. The temporal sequence of onset after chemotherapy administration suggested a possible drug-induced process.

Demonstration of polarizable crystals in fresh comedonal extracts: sebum crystallizes.

Previous studies using paraffin-embedded sections showed the presence of varying degrees of lipidic calculus (sebolith) formation in the pilosebaceous duct in acne comedonal lesions. The objective of this study was to examine the content of fresh acne comedonal extracts and pustules in polarizable crystalline material. Furthermore, to investigate if the amount of crystalline material correlates with the morphology, evolutionary stage, age and location of the comedone we performed polariscopic examination of 20 fresh acne comedonal extracts and 6 acne pustules.
