Laparoscopic resection of desmoid Type fibromatosis of the splenic hilum mimicking a greater curvature gastric GIST

Desmoid tumor, recently renamed as desmoid type fibromatosis, is an uncommon neoplasm. The mesentery is the usual origin of intra-abdominal desmoid-type fibromatosis and despite the fact there is no metastatic potential, it can infiltrate adjacent organs. There etiology remains unknown, preoperative diagnosis is difficult and differential diagnosis includes among other gastrointestinal stromal tumor [GIST]. In resectable tumors, the mainstay of treatment is surgical resection with at least clean microscopic margins. We present a case of a 51-year lady who presented with a 6.2 x 4.5 x 3.3 cm neoplasm in the anatomic area of the greater gastric curvature, the splenic hilum and the tail of the pancreas that was diagnosed as GIST on the CT scan. The patient was submitted to laparoscopic excision of the tumor and histopathological examination revealed desmoid type fibromatosis of the splenic hilum infiltrating the spleen, pancreatic tale and greater gastric curvature. According to the authors' knowledge, this is the first reported case of a sporadic splenic desmoid tumor, which has been treated successfully by laparoscopic en block resection

Fascial entrapment of the sural nerve and its clinical relevance / 대한해부학회지

Sural nerve presents great topographic variability and it is responsible for sensory innervation of the posterolateral side of the distal third of the leg and lateral aspect of the foot. Entrapment of the nerve could be caused by compression due to fascial thickening, while the symptomatology includes sensory alterations and deficits at the nerve distribution area. We report a cadaveric case of a variant sural nerve that presented a distinct entrapment site. A supernumerary sensory branch was encountered originating from the common peroneal nerve, while the peroneal component of the sural nerve was observed to take a course within a fibrous fascial tunnel 3.1 cm in length that caused nerve fixation and flattening. The tension applied to the aforementioned branch was shown to worsen during passive forcible foot plantaflexion and inversion. The etiology, diagnosis and the treatment options are discussed comprehensively.

Metachronous early gastric adenocarcinoma presenting coinstantaneously with complete remission of stage IV gastric MALT lymphoma

Adenocarcinoma and lymphoma represent the two most common malignant tumours of the stomach, with both neoplasms being associated with infection by Helicobacter pylori. However, the presence of lymphoma and adenocarcinoma in the same patient is a rare entity with synchronous neoplasms being more common than metachronous types. We report a case of stage IV gastric MALT lymphoma of the gastric angle with infiltration of the bone marrow successfully treated with chemotherapy and the occurrence of metachronous early gastric adenocarcinoma of the fundus presenting 1 year after the diagnosis of the lymphoma
