Eccrine mucinous nevus: clinical and histopathological description in an adult Nevus mucinoso ecrino en el adulto: descripción clínicohistológica.

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.

An usual elastophagocytic granuloma with involvement of the back: a possible variant of an annular elastolytic giant cell granuloma.

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.

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.

Granuloma por silicona líquida en regiones pretibiales tras su inyección en región glútea / Silicone granuloma in pretibial regions after its injection in gluteal region

En la actualidad, la inyección de materiales en el subcutáneo con fin estético es frecuente. Comunicamos el caso de una paciente con lesiones esclerodermiformesen ambas regiones pretibiales, en cuyo estudio histopatológico se observó un granuloma por silicona. Años atrás la paciente se había sometido ala inyección de un material de relleno en la región glútea. Se trata, por tanto, de un granuloma de cuerpo extraño por silicona que ha migrado a distanciadel lugar de la inoculación. El diagnóstico de este cuadro puede ser difícil. El tratamiento es complicado y, en general, no satisfactorio

Nowadays inoculation of materials for soft tissues augmentation is common. We report the case of a woman with sclerodermiform lessions in pretibialregions, characterized by a silicone granuloma. The histopathologic study in some years ago, she have seen inoculated of an unknown material in glutealregion. This case is a foreing body granuloma caused by silicone migrated from the inoculation site. Diagnosis of this conditions disease may bedifficult, and treatment is often unsatisfactory

Pénfigo vulgar en la infancia / Pemphigus vulgaris in childhood

El pénfigo vulgar en la infancia es muy infrecuente, con poco más de 50 casos descritos en la literatura. Presentamos un nuevo caso de pénfigo vulgar en un niño de 11 años, comentando su evolución y respuesta al tratamiento y revisamos los casos comunicados en este grupo de edad, con especial atención al manejo terapéutico y al pronóstico de esta enfermedad en la infancia

A new case of pemphigus vulgaris in an 11 years-old boy is reported. Pemphigus vulgaris is infrequent in childhood, with over 50 cases previously reported. We comment the evolution and the response to treatment. We reviewed other cases reported in children, with special attention to the therapeutic and the prognosis of the disease in childhood

Miasis foruncular importada por dermatobia hominis / Imported foruncular myiasis caused by dermatobia hominis

Dermatobia hominis y Cordylobia anthropophaga son los principales agentes etiológicos de miasis foruncular. Clínicamente se manifiesta como nódulos con un poro central por el cual puede observarse ocasionalmente la salida de la larva. Es un cuadro típico de zonas tropicales, que observamos en nuestro medio en turistas e inmigrantes. Presentamos un caso de miasis foruncular importado de Perú

The most common flies worldwide causing furuncular cutaneous myiasis are Dermatobia hominis and Cordylobia anthropophaga. Clinically this disease manifests nodular lesions containing a central pore, and sometimes the larva protrudes from the central opening. It is a disease typical of tropical areas, however it can also be seen in temperate zones in tourists and immigrants. Here we describe a case of furuncular myiasis imported from Peru

[Annular elastolytic giant cell granuloma: a case report located in non-sun exposed areas]. / Granuloma elastolítico anular de células gigantes: a propósito de un caso localizado en áreas no fotoexpuestas.

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.

Granuloma elastolítico anular de células gigantes: a propósito de un caso localizado en áreas no fotoexpuestas / Annular elastolytic giant cell granuloma: a case report located in non-sun exposed areas

El granuloma elastolítico anular de células gigantes (GEACG) es una entidad poco frecuente, caracterizada clínicamente por placas eritematosas anulares de centro atrófico e hipopigmentado, que predominan en zonas fotoexpuestas. En la histología presentan un infiltrado granulomatoso sin formación de imagen en empalizada, compuesto por linfocitos, histiocitos y células gigantes, con fagocitosis de fibras elásticas, sin necrobiosis ni depósito de mucina. Presentamos el caso de un paciente con manifestaciones clínicas atípicas en piel no fotoexpuesta, y una histología característica de GEACG
