RESUMO
Eccrine mucinous nevus is an uncommon hamartoma whose histological diagnosis is simple because of its peculiar morphological features, which include an increase in the number and/or size of the glands and eccrine ducts accompanied by abundant mucin deposits. When it presents with the typical symptom, focal hyperhidrosis, clinical suspicion is possible. El nevus mucinoso ecrino (NME) es un hamartoma escasamente reportado en la literatura cuyo diagnóstico histológico es sencillo debido a sus peculiares rasgos morfológicos, que incluye un aumento del número y/o tamaño de las glándulas ductos ecrinos acompañado de abundante depósito de mucina. Cuando presenta los hallazgos típicos, como la hiperhidrosis focal, es posible su sospecha clínica.

Annular elastolytic giant cell granuloma (AEGCG) is a very infrequent granulomatous dermatitis characterized by elastolysis and elastophagocytosis. It usually appears in middle-aged Caucasian women and is normally located in sun-exposed areas.We present a case of a 73-year-old woman with hypertension and type II diabetes, who was admitted to the hospital for an ischemic cerebrovascular accident. She presented with annular and serpiginous skin lesions on her back and arms that had appeared seven months earlier; a clinical and histological diagnosis of elastophagocytic granuloma was made. Our patient exhibited a florid presentation and a self-limiting course.

Cold panniculitis has been described in children and young women following cold exposure. Histopathologically, cold panniculitis shows a mostly lobular panniculitis, which consists of an infiltrate of lymphocytes and histiocytes in the fat lobules. Usually, the dermis shows a superficial and deep perivascular infiltrate mostly composed of lymphocytes, with no vasculitis. Inflammation is most intense at the dermal-subcutaneous junction. Differential diagnosis of cold panniculitis should be established with subcutaneous fat necrosis of the newborn, sclerema neonatorum, poststeroid panniculitis, chilblains, and frostbites.

Annular elastolytic giant cell granuloma (AEGCG) is an uncommon entity clinically characterized by erythematous annular plaques with atrophic and hypopigmented center, that predominates in sun-exposed zones. The histology shows a granulomatous infiltrate without palisading image, made up of lymphocytes, histiocytes and giant cells, with phagocytosis of elastic fibers, without necrobiosis or mucin deposit. We present the case of a male patient with atypical clinical manifestation on the non-sun exposed skin and AEGCG characteristic histology.
