The appearance of metastasis without clinically demonstrable primary tumor is one of melanoma's challenges. The aim of this study was to recognize the specific characteristics of this occurrence. Based on our study of three patients, we have proposed theories to explain this behavior, its clinical approach, and therapeutic management. We conclude by stressing the importance of finding the primary tumor or traces of it.

We report a case of necrobiosis lipoidica located on the glans penis of a patient without diabetes mellitus. Both clinical and histologic features favor the diagnosis of necrobiosis lipoidica, even though the location is unusual. Treatment with pentoxifylline was effective. The differential diagnosis is discussed.

Lumbosacral congenital cutaneous lesions have been recognized for a long time by neurologists and neurosurgeons as markers of occult spinal defects, but only a few cases have been published and discussed in the dermatologic literature. Based on a case report, we emphasize the importance of early diagnosis of these lesions, the use of new diagnostic techniques, and the correct management.

Skin affectation in patients infected by Toxocara spp. is rare even in endemic regions. We present a case of a patient that consulted us for a urticarial process and a personal history of eating rat cattle meat. After several studies, the diagnosis of secondary urticaria due to Toxocara spp. infection was made. Improvement of the symptoms was observed after treatment with thiabendazole.

Perianal basal cell carcinoma (BCC) is a rare tumour and only a few case reports can be found in the literature. In this location, it is important to differentiate a BCC from a basaloid cloacogenic carcinoma, as the first is an invasive but localized tumour, while the second has a high capacity for metastasis.

The inflammatory metastatic carcinoma is a rare clinical entity, histologically characterized by lymphatic dermal invasion by neoplastic cells. We report three cases of inflammatory metastatic carcinoma, two of them secondary to a breast carcinoma, and the third secondary to a colon adenocarcinoma.

The clinical and pathological findings in five patients with dermatomyositis are described. The diagnostic value of the cutaneous lesions in the disease, indicating the histological patterns of each cutaneous sign is stressed. Based in our experience and in the reviewed literature, we consider that Gottron's papules and poikilodermatomyositis present histological aspects that allow us to confirm the diagnosis suspected by clinical findings. Likewise we review some special difficult aspects of the disease such as infantile forms, association with neoplasias and overlap syndromes.
