Lymphangioleiomyomatosis (LAM) is a rare disease usually occurring in young women of child-bearing age. It is characterized by a distinctive proliferation of lymphatic smooth muscle cells, especially occurring in the pulmonary parenchyme. The majority of primary LAM occurs in the lung, but there are a few reports of extrapulmonary cases. We report a case of a 21-yr-old female who first complained of low abdominal pain and was referred from a local clinic with the impression of an ovarian cyst. Gynecologic ultrasonography revealed a large posterior pelvic mass with an irregular echogenicity measuring 9.7x4.2 cm in size. Pelviscopy showed a large, thin walled, partly cystic, pelvic mass. The mass was partly removed. Microscopically, the mass was characterized by a haphazard proliferation of smooth muscle cells arranged in fascicular, trabecular, and papillary patterns around a ramifying network of endothelium-lined spaces. The cells were plump or epithelioid with abundant eosinophilic cytoplasm and showed a positive reaction for both alpha-smooth muscle actin and HMB-45 antigen. Surgical and pathological findings were consistent with pelvic retroperitoneal LAM. Despite the numerous treatment attempts, the patient suffered from intractable chylous ascites and developed pulmonary LAM and died due to severe respiratory distress.

Carcinomas arising from an exstrophic urinary bladder are rare entities, and only seven such cases have been reported in the literature. We present the eighth case of advanced squamous cell carcinoma arising from an exstrophic bladder, with a pertinent review of the literature. The mean age of the patients was 54.9 years, with a male to female ratio of 3:1. The average duration of symptoms was 18.6 months. The appearance of a new growth was the most common symptom. Three patients had stage I disease, one patient each had stage II and III disease, two patients had stage IV disease, and the disease stage was not known in one patient. Five out of these eight patients underwent surgery. Four patients in the treatment group remained disease-free, with a mean survival period of 30 months. In conclusion, regular surveillance with cystoscopy is advised in all cases that had primary closure of the exstrophic bladder.

A 36-year old woman was admitted for menolipsis for 71 days and vaginal bleeding for 38 days and aggravation of vaginal bleeding with abdominal distension for 10 days. Gynecological examination revealed marked hysterauxesis without tenderness with a high HCG level. CT examination led to the misdiagnosis of trophoblastic tumor with lymph node metastasis of the left iliac vessels. The patient underwent subsequent laparotomy, and a huge pelvic hematoma with maximum diameter of 20 cm was found, for which left salpingectomy was performed. Pathologic examination of the surgical specimen supported the diagnosis of old tubal pregnancy. This case represents a rare clinical entity of old ectopic pregnancy manifested as a painless huge pelvic mass that can be easily misdiagnosed based on radiographical findings only.

We report here two cases of foreign body granulomas that arose from the pelvic wall and liver, respectively, and simulated recurrent colorectal carcinomas in patients with a history of surgery. On contrast-enhanced CT and MR images, a pelvic wall mass appeared as a well-enhancing mass that had invaded the distal ureter, resulting in the development of hydronephrosis. In addition, a liver mass had a hypointense rim that corresponded to the fibrous wall on a T2-weighted MR image, and showed persistent peripheral enhancement that corresponded to the granulation tissues and fibrous wall on dynamic MR images. These lesions also displayed very intense homogeneous FDG uptake on PET/CT.
