Primary Hepatic Lymphoma Presenting as an Acute Abdomen in a Young Female Patient: A Case Report and Literature Review.

We report a rare case of primary hepatic lymphoma (PHL) in a hepatitis B virus- (HBV-) infected young female patient who presented with right upper abdominal pain, nausea, and vomiting for a few days. The preoperative diagnosis was difficult due to the rarity of the disease and the presence of a solitary hypodense mass in the left lobe of the liver on contrast-enhanced computed tomography (CT) scan with a normal alpha-fetoprotein (AFP) and negative cytology. She underwent an uneventful extended left hemihepatectomy, and the surgical biopsy revealed a PHL-of diffuse large B-cell lymphoma (DLBCL) type-with negative resection margins. She received adjuvant combination chemotherapy and remained disease-free with normal serial radiology over a 2-year follow-up period.

Granular cell tumor of the gallbladder: case report and review of the literature.

BACKGROUND: Granular cell tumors (GCTs) are rare benign tumors, which originate in the tongue, ovary, oropharynx, GIT and respiratory tract. Biliary GCTs are rarities. Clinical presentations depend on tumor site. CASE REPORT: A 62-year-old male, presented with acute and severe abdominal pain for fifteen days. He was in pain, not pale or jaundiced. Abdominal imaging showed thick-walled gallbladder with multiple stones suggestive of calcular cholecystitis and liver cirrhosis. The diagnosis of acute-on-chronic cholecystitis was made. Following informed consent open cholecystectomy showed a cirrhotic liver with enlarged Calot's lymph node and thick adhesions. Histopathology revealed a benign GCT of the gallbladder. The patient recovered uneventfully. The patient was well with no tumor recurrence after one year follow up. CONCLUSION: GCT of the gallbladder should be considered in patients presenting as acute-on-chronic cholecystitis without imaging evidence of tumor. Surgical removal with wide safety margins should be contemplated.

Surgical treatment of mucocele of the appendix: a systematic review and case report.

INTRODUCTION: Appendicular mucocele is a rare well-described clinico-pathological occurrence. It denotes an obstructive dilatation of the appendicular lumen by mucinous secretions. CASE REPORT: A 60-year-old patient presented with right lower abdominal pain and nausea for 2 years. Abdominal CT scan suggested a diagnosis of a appendicular mucocele. Following informed consent, surgical exploration revealed a cystic mass arising from the body of the appendix with inflamed walls with no evidence of perforation. Simple appendectomy was performed as the caecum and the mesenteric nodes were free of pathological involvement. The final diagnosis of mucinous cystadenoma was confirmed by histopathology. Postoperative course was uneventful. The patient was in good health during a four years regular follow-up. DISCUSSION: Appendicular mucocele is a rare disease with vague symptoms. Abdominal imaging is an important diagnostic tool, but histopathology is the standard for definitive diagnosis. Surgery for benign appendicular mucoceles has an excellent long-term prognosis.
