Non-Hodgkin′s lymphoma "masquerading" as Pott′s disease in a 13-year old boy

Abstract

Lymphomas are malignant neoplasms of the lymphoid lineage. They are broadly classified as either Hodgkin disease or as non-Hodgkin lymphoma (NHL). Burkitt′s lymphoma, a variety of NHL, is significantly most common in sub-Saharan Africa, where it accounts for approximately one half of childhood cancers. Lymphoblastic lymphoma is less common. A case of paravertebral high grade non-Hodgkin′s lymphoma (lymphoblastic lymphoma) "masquerading" as Pott′s disease in a 13-year-old child is reported. The present report was informed by the unusual presentation of this case and the intent of increasing the index of diagnostic suspicion. A brief appraisal is provided of the clinical parameters, management strategies and challenges. AT was a 13-year boy that presented on account of a slowly evolving and progressively increasing hunch on the back and inability to walk over 4 and 8 months duration, respectively. There was subsequent inability to control defecation and urination. There was no history of cough. He and his twin brother lived with their paternal grandfather who had chronic cough with associated weight loss. The grandfather died shortly before the child′s admission. The child had no BCG immunization. The essential findings on examination were in keeping with lower motor neurons (LMN) paralysis of the lower limbs. The upper limbs appeared normal. There was loss of cutaneous sensation from the umbilicus (T10) downward. There was a firm, (rather tense), non-tender non-pulsatile, smooth swelling over the mid-third of the back (T6-L1) the mass had no differential warmth. It measures about 20×12 cm. Chest radiograph showed no active focal lung lesion, but the thoraco-lumbar spine showed a vertebral planner at L1 and a wedged collapse of T11-T12 vertebrae. There was sclerosis of the end plates of all the vertebral bodies with associated reduction in the bone density. He had an excision biopsy on the 90th day on admission, following which his clinical state rapidly deteriorated. He died within 48 h post surgery. This report aims at raising the local index of clinical suspicion by highlighting the reality of rarities, even in the presence of inadequate diagnostic facilities!
