Background: The presence of granuloma, visualized in histopathology for diagnosing tuberculosis in tissue samples, is not a specific finding. Moreover, histopathological examination of tissue sections needs one to two weeks for final reporting. A rapid and sensitive method is therefore needed for detection of Mycobacterium tuberculosis in these paucibacillary tissue samples. Methodology: A PCR-assay specific for IS6110 was evaluated for 104 different tissue samples in comparison to histopathology that was considered gold standard. Results: PCR showed 74.1% sensitivity and 96.1% specificity. False positive and false negative results were observed in three (2.88%) and seven (6.73%) samples, respectively. Positive agreement between histopathology and PCR was observed as 0.737, indicating substantial good agreement between two tests. Conclusions: PCR can be used for early diagnosis of tuberculosis in tissue samples that can help to initiate timely anti-tubercular treatment and prevent progression to irreversible changes.

Neural fibrolipoma is an uncommon tumor-like lesion that involves the upper extremity and usually arises in the median nerve. It is associated with macrodactyly in one-third of the cases. A 3-year-old girl presented with increasing size of fingers of both the hands since birth. Clinical examination revealed macrodactyly of two fingers of the right hand and three fingers of the left. Surgical reduction was performed and microscopy of the biopsy specimen established the diagnosis of neural fibrolipoma. Knowledge of the clinicopathological features is necessary for accurate diagnosis and treatment of this rare entity.

We are reporting a rare case of severe hemolytic disease of newborn (HDN) with Bombay phenotype mother. A retrospective study of a case with severe haemolytic disease of newborn with Bombay phenotype mother was done. Blood grouping, antibody screening, and lectin study was done on the blood sample of the baby and mother to confirm the diagnosis. Hematological and biochemical parameters were obtained from the hospital laboratory information system for the analysis. Blood group of the baby was A positive, direct antiglobulin test was negative. Blood group of the mother was confirmed to be Bombay phenotype, Hematological parameters showed all the signs of ongoing hemolysis and the bilirubin level was in the zone of exchange transfusion. Due to the unavailability of this rare phenotype blood unit, baby was managed conservatively. Anticipating the fetal anemia and HDN with mothers having Bombay phenotype and prior notification to the transfusion services will be of great help in optimizing the neonatal care and outcome.
