ABSTRACT
Introducción: El fibroadenoma es una lesión bastante común en mama, pero su localización en la región vulvar es extremadamente rara, con alrededor de sesenta casos, descritos en la literatura. Se presenta como una masa unilateral, subcutánea y asintomática, de crecimiento insidioso. El tamaño de este tipo de lesión varía entre 1 y 12 cm en los casos reportados hasta la fecha. A pesar de ser infrecuentes, las tumoraciones a nivel vulvar continúan siendo importante motivo de consulta. La histogénesis de este tipo de lesiones ha sido tema de discusión en los últimos años, sobresalen dos teorías: la presencia de tejido mamario ectópico, y la degeneración tumoral de un grupo de glándulas similares a tejido mamario, descritas como componente habitual de la región. Objetivo: Aportar un diagnóstico diferencial polémico de tumores vulvares. Presentación del caso: Se presenta una paciente de 22 años con diagnóstico histopatológico de fibroadenoma de vulva. Se realiza exéresis de la lesión, la cual al examen macroscópico midió aproximadamente 15 cm en su eje longitudinal (la más grande reportada en la literatura). Conclusiones: A pesar de su baja frecuencia de presentación, el fibroadenoma de vulva es una entidad a tener en cuenta como diagnóstico diferencial de los tumores subcutáneos de localización vulvar(AU)
Introduction: Fibroadenoma is a fairly common lesion in the breast tissue, but its location in the vulvar region is extremely rare, with about 60 specific cases in the literature. It is presented as a unilateral, subcutaneous and asymptomatic mass, with insidious growth. The size of this type of lesion is between 1 and 12 cm in the cases reported to date. Despite being infrequent, vulvar tumors continue to be important reasons for medical consultation. The histogenesis of this type of lesions has been the subject of discussion in recent years; two theories stand out: the presence of ectopic breast tissue, and tumor degeneration of a group of glands similar to breast tissue described as a common component of the region. Objective: To providea polemic differencial diagnosis of vulvar tumors. Case presentation: We present a 22-year-old patient with histopathological diagnosis of vulvar fibroadenoma. Excision of the lesion was performed, which at the macroscopic examination measured approximately 15 cm in its longitudinal axis (the largest reported in the literature). Conclusions: Despite its low frequency of presentation, vulvar fibroadenoma needs to be considered as differencial diagnosis of vulvar tumors(AU)

Mammary-like glands are poorly recognized structures of normal vulvar skin. Here, we report the first case of primary mammary-like gland adenocarcinoma of the vulva in Korea and discuss the differential diagnosis and treatment of this rare tumor. A 62-year-old woman presented with an itching sensation and palpable mass of the vulva. Abdominal computed tomography showed multiple variable-sized nodules with peripheral rim enhancement in the liver. The pathology of the vulva and liver lesions was consistent with invasive ductal carcinoma of the breast, with positive staining for estrogen receptors, progesterone receptors, HER-2, and GCDFP-15. Ultrasonography and magnetic resonance imaging of the breast were normal. Given the histological findings in conjunction with the absence of a breast lesion, a diagnosis of primary mammary-like gland adenocarcinoma of the vulva was made. She died of pneumonia 7 weeks after the diagnosis.

Fibroadenoma is a rare lesion of the vulva. It has been proposed that the origin of the tissue is either ectopic breast tissue or vulvar mammary-like glands (MLG). We report a case of vulvar fibroadenoma in a 33-year-old woman with a right vulvar mass presenting clinically as vulvar cyst. The cut surface of the tumor showed a white and homogenous appearance that was 2.5 cm in maximum dimension. Microscopically, the lesion was well-circumscribed but non-encapsulated. It revealed nodular, glandular and stromal proliferation, consistent with fibroadenoma of breast. Immunohistochemical staining for the estrogen receptor and progesteron receptor revealed nuclear positivity in the epithelium. Smooth muscle actin confirmed the presence of a myoepithelial cell layer. Staining for pancytokeratin showed epithelial cytoplasmic positivity.

We describe a 38-year-old woman with an adenoma of anogenital mammary-like glands on the left labium major. Adenomas of anogenital mammary-like glands have been rarely reported with various nomenclatures in the English literature. The knowledge of this rare disease entity may be important to diagnose and treat the lesions arising on the anogenital areas.
