Tumor de células de la granulosa de tipo adulto. Un caso raro de tumor testicular. Presentación de un caso / Adult type granulosa cell tumor: a rare testicular neoplasm. A case report

Los tumores de células de la granulosa (TCG) pertenecen al grupo de tumores del estroma y cordones sexuales de las gónadas. Se distinguen 2 tipos: juvenil y adulto. Los TCG de tipo adulto testicular son extremadamente raros, y solo un pequeño número de casos han sido publicados. Su comportamiento biológico es incierto, con casos descritos de metástasis a distancia años después de su presentación inicial. Su diagnóstico se basa en el reconocimiento de las características citológicas y arquitecturales descritas en su homólogo ovárico, ya que ambos son morfológicamente indistinguibles. Describimos un nuevo caso de TCG de tipo adulto testicular en un varón de 23 años, haciendo hincapié en su comportamiento clínico, así como en las características inmunofenotípicas de este raro tumor (AU)

Granulosa cell tumors (GCT) belong to the group of sex cord-gonadal stromal tumours. Two types can be differentiated: juvenile and adult. Adult testicular GCT are extremely rare with only a small number of published cases. Their biological behaviour is not completely clear with cases of distant metastasis appearing years after the initial diagnosis. Diagnosis is based on the cytological and architectural characteristics described in its ovarian counterpart, since both are morphologically indistinguishable. We present a further case of GCT of the adult type in a 23 year old man. We discuss the clinical behavior and immunophenotypical characteristics of this rare tumour (AU)

Tratamiento quirúrgico de una úlcera vulvar aguda de Lipschütz / Surgical treatment of an acute vulvar ulcer of Lipschütz

La úlcera de Lipschütz es un proceso ulcerativo vulvar agudo, considerado dentro del grupo de las aftosis. Suele darse en niñas o en mujeres jóvenes. No está en relación con enfermedades venéreas. Sí se ha considerado el antecedente de infección reciente por el virus de Epstein-Barr.El proceso, que cursa como una úlcera de aparición brusca, es sumamente doloroso y suele responder bien al tratamiento local y sistémico con corticoides. Presentamos en este trabajo un caso en el que el fracaso del tratamiento médico nos obliga a ensayar la opción quirúrgica (AU)

Lipschütz ulcer is an acute vulvar ulcerative process, considered to belong to the group of aphthous ulcers. It usually occurs in female children or young women. This ulcer is not associated with venereal disease but has been associated with a recent history of the Epstein-Barr virus. The process, which presents as an ulcer flare-ups, is extremely painful and usually responds well to local and systemic steroid therapy. If medical therapy is unsuccessful, surgical treatment is required (AU)

Nodular and diffuse fibrous proliferation of the penis and tunica vaginalis.

Fibrous benign proliferations of the testis and paratesticular tissues are an uncommon and heterogeneous group of lesions that can mimic true neoplasms. Among them, those considered to be reactive proliferations have been included in the category of fibrous pseudotumors and are often associated with trauma, hydrocele, or infection. We report 2 cases of nodular and diffuse fibrous proliferation. This condition is part of the spectrum of reactive benign fibrous lesions and has previously been described in the testicular tunics and paratesticular region only. One of our 2 cases had the peculiarity of being located in the penile shaft, whereas the other involved the tunica vaginalis. To the best of our knowledge, this is the first report of a diffuse and nodular fibrous tumor involving the penis.
