Granulomatous Mastitis Due to Non-Tuberculous Mycobacteria: A Diagnostic and Therapeutic Dilemma.

Non-tuberculous mycobacterial (NTM) infections of the breast are rare. These infections present as cellulitis of the breast or breast abscess. Their diagnosis poses a challenge as they manifest signs of acute inflammation, unlike tuberculous mycobacterial infections which present in a chronic pattern. However, on aspiration of pus from the site of infection, primary smear may show acid fast bacilli. This poses a diagnostic dilemma. The present case is that of a 34-year-old woman who presented with recurrent mastitis. She had history of right breast swelling, for which surgical excision had been performed three months prior at another facility. Her histopathology had showed cystic granulomatous neutrophilic mastitis (CNGM). The patient again presented with right breast abscess which was confirmed on ultrasonography. Incision and drainage along with removal of necrotic tissue was done. Primary smear of pus showed acid fast bacilli on Ziehl-Neelson staining. Bacterial culture and line probe speciation revealed non-tuberculous mycobacterium M. abscessus, which responded well to prolonged anti-microbial therapy. These rapidly growing NTM require prolonged treatment and are quite often recurrent. M. abscessus is a rare cause of CNGM, with this being only the third reported case in literature. A brief case report with a review of literature is presented.

Gallstone Ileus: Dilemma in the Management.

Gallstone ileus is a mechanical intestinal obstruction caused due to impaction of a large gallstone within the bowel. The ideal treatment of gallstone ileus remains controversial, with the main dilemma being between a one-stage and a two-stage surgical procedure. A 69-year old male patient presented with gallstone ileus. A one-stage procedure with enterolithotomy and primary closure of duodenal fistula was done. His immediate postoperative recovery was uneventful, but after 3 weeks of surgery, he developed respiratory complications and expired of multi-organ failure. In gallstone ileus, patient presents with symptoms of intestinal obstruction. Enterolithotomy alone remains the most common operative method, but the definitive surgical management is still under research. An intraoperative dilemma between a one-stage or two-stage surgery is difficult to resolve in absence of clear guidelines. Hence, more studies are required to come to a consensus in deciding its definitive management.
