Pseudomyxoma extraperitonei: a rare presentation of a rare tumour.

Pseudomyxoma extraperitonei is rare lesion resulting from the rupture of an appendiceal mucocele into the extraperitoneal tissues. We report a case of an 80-year-old woman with a medical history for a left hemicolectomy and a laparoscopic cholecystectomy 11 and 6 years, respectively, referred to our hospital for abdominal pain of increasing severity localised to the right hemiabdomen. The abdominal examination revealed a mobile mass a multidetector CT was performed; the patient was taken to surgery which was performed with no complications. Histopathological analysis of the tumour reported a pseudomyxoma associated to a moderately differentiated adenocarcinoma. The patient remains asymptomatic at a 1-year follow-up.

Glomus tumour of the stomach: an unusual cause of gastrointestinal bleeding.

Glomus tumours are a rare type of subepithelial mesenchymal tumours that present in deep visceral organs such as the stomach, which are difficult to diagnose. We report a case of a 44-year-old woman with diabetes who presented with anaemia, abdominal pain and melena diagnosed preoperatively with a gastric glomus tumour initially misdiagnosed as a gastric ulcer located at the lesser curvature. Upon referral to our centre a repeat endoscopy and biopsy were performed. A partial gastrectomy was performed with no complications. Histopathological analysis of the tumour reported clear margins and immunostaining was positive for smooth muscle actin and collagen IV. The patient remains asymptomatic at 3-month follow-up.
