RESUMO
Hydatid disease, also known as Echinococcosis is a zoonosis caused by the larval stage of Echinococcus. The human cystic variant primarily affects liver and lungs. The pelvic location of the disease is a rare finding usually secondary to a ruptured liver cyst, although it may also appear as a primary lesion affecting the genital organs. Despite its rarity, in endemic areas, pelvic hydatid disease should be considered in the differential diagnosis of complex adnexal cystic mass, to make an appropriate treatment strategy. The suspected diagnosis is based on imaging studies and serodiagnostic techniques, in which a new field of research attempts to find a standardized test with sufficient sensitivity and specificity. We report a case of primary pelvic hydatid disease in postmenopausal women operated for suspected ovarian cancer.

Presentamos el caso de un paciente con una de las hiperpigmentaciones cutáneas menos frecuentes, la hipermelanosis lineal y espirilada. Esta entidad se caracteriza por la aparición progresiva durante los dos primeros años de vida, de manchas hiperpigmentadas lineales y en remolinos siguiendo las líneas de Blaschko, sin clínica inflamatoria asociada. Histológicamente se observa una hiperpigmentación difusa de la capa basal de la epidermis y melanocitos prominentes o vacuolados, sin incontinencia del pigmento o melanófagos dérmicos. Esta alteración debe ser diferenciada de la incontinencia pigmenti, los nevos epidérmicos sistematizados, la hipomelanosis de Ito y de las quimeras o mosaicismos cromosómicos (AU)
We present the case of unusual skin hyperpigmentation called linear and whorled hypermelanosis. This pathology is characterized by the progressive appearance during the first two years of life of linear and whorled hyperpigmentation following Blachko lines, without previous inflammatory events. The histologic examination shows an increased diffuse hyperpigmentation of the basal layer of the epidermis and prominent or vacuolation of melanocytes, with no pigment incontinence or dermal melanophages. This condition must be differentiated form incontinentia pigmenti, early systematized epidermal nevus, hypomelanosis of Ito and chimerism or mosaicism (AU)
