Histiocytosis in a 7 year old boy, a diagnostic dilemma

Histiocytoses are a group of rare disorders which are characterized by the infiltration/accumulation of histiocytic cells in affected tissues. Their mode of clinical presentation varies greatly and can represent a diagnostic challenge in our environment where there is a paucity of diagnostic facilities. This report is on a 7 year old boy with probable Histiocytosis who initially presented with signs and symptoms suggestive of pulmonary tuberculosis. Difficulties in reaching a conclusive diagnosis of the type of histiocytosis coupled with financial limitations contributed to the eventual demise of this patient.
