[Small pelvis lipoma spreading to the gluteal region]. / Lipoma malogo taza i yagodichnoi oblasti.

We present a 36-year-old woman with small pelvis lipoma spreading to the gluteal region through the greater sciatic foramen. Resection of lipoma was performed via two accesses (lower median laparotomy and semilunar incision in the gluteal region). The tumor was the content of sciatic hernia that is extremely rare. Combination of surgical approaches can provide favorable outcomes in these patients.

[Pancreatic mucinous cystadenoma with atypical clinical presentation]. / Mutsinoznaya tsistadenoma podzheludochnoi zhelezy ­ netipichnyi variant techeniya zabolevaniya.

We present a 33-year-old patient with atypical clinical course of pancreatic mucinous cystadenoma. The tumor had connection with pancreatic ductal system and led to bleeding into cystic cavity. This contributed to incorrect preoperative diagnosis of post-necrotic cyst. The final diagnosis of mucinous cystadenoma was established after histological examination. Distal pancreatectomy excluded incorrect treatment.
