Laparoscopic Resection of Isolated Retroperitoneal Gastric Duplication Cyst in an Infant.

We, herein report a rare case of retroperitoneal gastric duplication cyst in a 5-month female infant presenting with antenatal diagnosis of right renal cyst. Post-natal evaluation showed presence of retroperitoneal cyst in the region of right adrenal gland, which progressively increased in size on serial imaging. Laparoscopic resection resulted in satisfactory recovery. Intra-operative findings and histopathology confirmed diagnosis of isolated retroperitoneal gastric duplication cyst. Authors present the clinical features of this rare entity along with feasibility of successful laparoscopic excision in infantile age group.

Unusual benign polypoid and papular neoplasms and tumor-like lesions of the vulva.

We aimed to investigate the prevalence and spectrum of unusual benign neoplasms and tumor-like lesions presenting as vulvar polyps and papules, to study their clinical, pathologic, hormonal, and developmental features and whether they have important associations with other pathologic lesions or clinical diseases. We conducted a retrospective review study of 115 vulvar specimens over 7 years. Common lesions, for example, fibroepithelial polyps, skin tags, papillomas, abscesses, viral warts and common cysts, were excluded. We found 21 cases (18%) with uncommon benign vulvar lesions. They included 7 epithelial cysts, 3 vascular lesions, 3 glandular neoplasms, 3 endometrioses, 1 caruncle, 1 pilonidal sinus, 1 prolapsed urethra, 1 seborrheic keratosis, and 1 granular cell tumor. The age range was between 1 and 64 years with a mean age of 33 years. Most (86%) were 2.5 cm or less. Many were asymptomatic incidental pathologic findings that can be missed clinically. Nine cases have important clinical associations or coexisting incidental pathologic lesions. Some lesions demonstrated hormone receptors. Some were clinically confused with fibroepithelial polyps, abscesses, warts, melanocytic lesions, and tumors. In conclusion, although the vulva is a small compartment, its developmental and histologic complexity can result in a variety of unusual and rare benign polypoid and papular lesions, some unique to the vulva, which might present diagnostic challenges to the clinicians and pathologists. In addition, many bear controversy regarding their histogenesis and origin of development in the vulva.
