[Cutaneous ciliated cyst of the scrotal skin. A case report with discussion of pathogenesis]. / Quiste cutáneo ciliado en piel escrotal. Descripción de un caso con discusión patogénica de la entidad.

Cutaneous ciliated cyst (CCC) is a rare benign lesion predominantly occurring in the lower limbs of young women and exceedingly rare in males. Here, we report a case involving a previously unreported site (i.e., scrotal skin) in a 15-year-old male. We also describe pathologic and immunonohistochemical findings, review the pertinent literature and discuss their pathogenetic mechanisms. We propose that CCC could represent a morphologic pattern encompassing several pathogenetically different entities. Data we provide support the hypothesis that at least a part of CCC, specially those occurring in males, could have their origin in ciliated metaplasia of apocrine sweat glands.

El quiste cutáneo ciliado (QCC) es una lesión benigna muy infrecuente, que aparece predominantemente en extremidades inferiores de mujeres jóvenes. En varones es una lesión aún más rara. En esta nota se presenta un caso de quiste cutáneo ciliado en piel escrotal de un varón de 15 años, se describen características histológicas e inmunohistoquímicas, se revisa la bibliografía al respecto y se realiza una discusión patogénica de la entidad. Se plantea que el QCC puede ser en realidad un patrón morfológico que engloba varias entidades patogénicamente diferentes. Los datos aportados en nuestro caso apoyan la teoría de que al menos un grupo de QCC, y en especial los acaecidos en pacientes de sexo masculino, podrían tener su origen en la metaplasia ciliada de glándulas sudoríparas apocrinas (AU)

[Granular cell tumour of prostate diagnosed by transrectal biopsy. Which therapeutic attitude?]. / Tumor de células granulares de próstata diagnosticado en biopsia transrectal. Qué actitud tomar?

Granular cell tumour (GCT) is not an uncommon tumour of neural origin usually located on subcutaneous tissues and oral cavity. In prostate gland is exceptional, with only one case reported on the indexed literature of the last three decades. We report a case of a 63-year-old man presented with urinary complaints, enlarged prostate and increased PSA levels. The patient subsequently underwent transrectal needle biopsy which revealed GCT. The clinicpathological dilemma originated after this diagnosis is discused and the most suitable follow-up is proposed.
