Chronic postoperative wound infection caused by Myocobacterium fortuitum complex.

Mycobacterium fortuitum in a rapidly growing atypical mycobacteia, sometimes associated with nosocomial infections in human. These infections are often difficult to identify; and treat even after indentification. We report here a case of chronic post operative wound infection due to M. fortuitum.

Langerhans cell histiocytosis of the mandible in a six-year-old child.

Histiocytosis is a term applied to a group of rare disorders of the reticuloendothelial system. Eosinophilic granuloma, the most benign and localized of the three Langerhans cell histiocytosis entities, may be solitary or multiple. Eosinophilic granuloma can affect almost any bone, but commonly involves the mandible when the jaws are affected. Conventional treatment of LCH is with surgery, radiotherapy, chemotherapy and steroid injections, alone or in combination. Spontaneous regression of localized disease has also been reported. We report a six and a half-year-old patient with Langerhans cell histiocytosis--solitary eosinophilic granuloma of the mandible that initially regressed but rapidly recurred even after radical treatment and had a fatal outcome.
