RESUMO
Acute lymphoblastic leukemia (ALL) can occasionally relapse in unusual extramedullary sites like bone. Here we present a 6.5-year old boy with 'T' cell ALL who developed a swelling in left tibia which was infiltrated with lymphoblasts 7 months after completion of chemotherapy. Bone marrow and cerebrospinal fluid were negative for blasts. This is the first reported case of bone relapse in ALL from India. We discuss the previous cases of isolated bone relapse in ALL reported in English literature.

Adenoid cystic carcinoma (ACC) of the lacrimal gland is a rare tumor from the epithelial structure. It is rare in children. The authors report a case of ACC in a girl child. Extensive excision of the tumor is advised to prevent later recurrences. Local control can be better achieved by a combination of radiochemotherapy as ACC has been shown to recur event after 10 years.

OBJECTIVE: In order to study the clinical profile of children presenting with superior vena cava syndrome (SVCS), case records of all children presenting with SVCS over a 10-year period were retrospectively analyzed. METHODS: Twenty one children (20 males and 1 female) with a median age of 10.0 years (range 5.0 to 12.0 years) were detected to have an underlying hematological malignancy. T-cell acute lymphoblastic leukemia accounted for a major share (57%) in the underlying etiology; 33% of the subjects had non-Hodgkin's lymphoma (T-cell lymphoblastic lymphoma). RESULT: No Patient required radiotherapy or urgent thoracotomy. Among survivors (n=11), who were alive and well at the time of writing this report, the median follow-up was 6.5 years, (range 0.5-9.6 years). T-cell ALL and lymphoblastic lymphoma are common underlying causes of SVCS in Indian children. CONCLUSION: The value of diagnostic interventions performed under local anaesthesia and prebiopsy corticosteroids usage was found to be reassuring since long-term survival without disease is achievable.
