Report of a Primary Testicular Embryonal Rhabdomyosarcoma.

Primary testicular rhabdomyosarcoma is a rare pediatric genitourinary tumor with few cases reported in the literature. The clinical presentation is identical to that of other common testicular neoplasms. Diagnosis entails careful microscopic examination and immunohistochemical analysis to rule out other primary testicular malignancies. Treatment consists of radical orchiectomy and adjuvant chemotherapy with possible retroperitoneal lymph node dissection. This multimodal approach is required to improve survival outcomes and reduce disease recurrence. We present the case of a primary testicular embryonal rhabdomyosarcoma in a 19-year-old male who presented with a rapidly, enlarging, painless testicular mass. He was treated with radical orchiectomy and adjuvant chemotherapy. Once found with metastatic disease, he then received salvage chemotherapy and radiotherapy without success.

Intestinal endometriosis as a cause of rectal bleeding: a case report.

Endometriosis is the presence of endometrial glands and stroma outside the uterine cavity and musculature. The estimated prevalence of endometriosis in Puerto Rico is 4.0%. The exact prevalence of extra-pelvic endometriosis is unknown. It has been reported that affects the intestinal tract in 3-37% of all patients with pelvic endometriosis, with the sigmoid colon and rectum being the most commonly involved areas. It can mimic colorectal cancer by producing an invasive abdominal mass. We present the case of a 40 y/o female patient with rectal bleeding that presented a mass on a colonoscopy highly suggestive of cancer. After all the studies and an exploratory laparotomy, the diagnosis was intestinal endometriosis. Because of lack of published data about intestinal endometriosis in Puerto Rico, it is very important to show this condition in order to properly assess young women with rectal bleeding in light of a clinical suspicion of endometriosis.
