Synchronous occurrence of appendiceal mucinous cystadenoma, with colon adenocarcinoma and tubulovillous rectal adenoma: Management and review of the literature.

Appendiceal mucocele (AM) is a rare clinical entity comprising 8% of all appendiceal tumors, and it is seen in 0.2-0.3% of all appendectomy specimens. Apart from sporadic cases, there are no enough published data about the incidence of synchronous appendiceal tumors in patients with colorectal cancer. We describe a very rare case of synchronous occurrence of AM, colon adenocarcinoma, and tubulovillous adenoma of the rectum and review the relevant literature. We conclude that thorough preoperative and perioperative evaluations are mandatory in patients undergoing surgery for colorectal cancer to exclude a synchronous colon or an appendiceal primary tumor. Larger prospective studies are necessary to accurately determine the incidence of synchronous appendiceal tumors and colorectal cancer.

Cutaneous metastasis of transitional cell bladder carcinoma: a rare presentation and literature review.

Cutaneous metastasis from transitional cell bladder carcinoma is a rare clinical entity associated with poor prognosis. We present a case of cutaneous metastasis arising from a transitional cell bladder carcinoma in a male patient who had undergone a radical cystectomy and bilateral ureterostomy 17 months previously. The cutaneous metastasis became evident 3 months before the manifestations of generalized recurrent disease. An awareness of this rare clinical entity and high index of suspicion is needed to rule out metastatic spread in patients with a previous history of transitional cell bladder carcinoma presenting with cutaneous nodules. Definitive diagnosis requires a histological confirmation, but prognosis is generally poor.

Bilateral polyorchidism associated with intraabdominal cryptorchidism: a case report.

OBJECTIVE: The aim of this study was to present a rare congenital anomaly of polyorchidism and to review the current management. CLINICAL PRESENTATION AND INTERVENTION: We report the case of a 19-year-old man who was referred for the treatment of an indirect left inguinal hernia. The ultrasound demonstrated a testis on the right side with an additional mass. The preoperative laboratory studies were normal. At surgery, a solid mass consistent with an ectopic testis was removed. The histological evaluation showed the presence of a fourth testis without malignancy, confirming the diagnosis of bilateral, double testes associated with intraabdominal cryptorchidism, which was removed for histology. The postoperative endocrinological evaluation revealed hypergonadotrophic hypogonadism. The patient was followed up conservatively. CONCLUSION: Polyorchidism should be included in the differential diagnosis of a solid extratesticular mass, and its management should be conservative.
