[Intraparenchymatous vascular tumors of the testicle: report of a new case of cavernous hemangioma]. / Tumores vasculares intraparenquimatosos de testículo: aportación de un nuevo caso de hemangioma cavernoso.

The occurrence of a vascular tumour at the intraparenchymatous testicular level is a fact little reported in the literature. Searching for such events, 19 cases were found all of which showed benign clinical behaviour. The most commonly seen histological pattern is cavernous haemangioma (11 patients). Mean age at presentation is 19 years old and the most usual pre-operative diagnosis, germinal cell neoplasia. Since there are no specific ultrasound patterns that may allow to differentiate benign from malignant masses, inguinal orchiectomy is the choice treatment in this type of lesions. Furthermore, the case of a 44-year old patient with hypoechogenic solid mass in left testis who consulted for sporadic episodes of long-standing scrotal pain is presented. After radical exeresis of the gonad, the histological analysis showed existence of testicular cavernous haemangioma.

[Retroperitoneal ganglioneuroma]. / Ganglioneuroma retroperitoneal.

Presentation of one case of retroperitoneal ganglioneuroma in a 31-year old female. This type of neoformation, with origin at the sympathetic system nodes level, is considered to be the benign homologous of neuroblastoma. Peak incidence age ranges from 3 to 20 years. The retroperineum is one of the most frequent sites, second only to the mediastinum. Diagnosis is normally casual and is considered definite when, following mass removal and completion of the pathoanatomical study, the presence of neuroblasts in the tumour can be ruled out.

[Acute scrotum: unusual presentation of Schönlein-Henoch purpura]. / Escroto agudo: un modo de presentación insólito de la púrpura de Schönlein-Henoch.

Being a systemic vasculitis, Schöenlein-Henoch purpura may affect the scrotum and its content. According to the series studied, this occurs in about 10% patients (2-38%) and sometimes requires a differential diagnosis with the spermatic cord torsion. An isotopic study with 99Tc may avoid a surgical procedure quite often unnecessary. In the case reported here, vasculitis presented as an acute scrotum, which is highly infrequent in the literature and makes a correct presumption diagnosis extraordinary difficult.
