LAMN as a differential diagnosis for abdominal pain: a case report from Syria.

Low-grade appendiceal mucinous neoplasms (LAMNs) are papillary or flat mucinous tumors with low-grade cytologic atypia found in <0.3% of appendectomy specimens among older population. They are the most frequent source of pseudomyxoma peritonei.

Case report: actinomycosis of the abdominal wall.

Primary abdominal wall actinomycosis is rare, but even rarer when it comes to intestinal infiltration; it is usually misdiagnosed as a neoplasm in computed tomography till proved otherwise with pathological examination. We report a 59-year-old diabetic male presented with a year-old abdominal wall mass, diagnosed by pathology after surgical excisional biopsy, and treated with penicillin for 6 months. We recommend consideration of actinomycosis in cases of abdominal wall mass, especially in immunocompromised patients, as a differential diagnosis of neoplastic lesions.
