Inflammatory myofibroblastic tumor (IMT) is a rare entity of neoplastic origin. It usually occurs in children and adolescents and most commonly involves pulmonary and gastrointestinal sites. Here, the authors present two cases; one is the nine months old boy with a subcutaneous IMT in the left temporal region that was treated successfully with surgical resection. To the best of our knowledge, this is the first reported case of a subcutaneous IMT in this particular region. The second is an eight years old girl with an IMT of the right hemi-pelvis. The mass had complete surgical excision with clear margins and no residual disease. She was kept on regular follow-up with ultrasound abdomen. However, her disease relapsed with the appearance of lesions in right iliac fossa, right ovary, and liver. Biopsy of the relapsed abdominal mass confirmed ALK-positive IMT. She was treated with ALK inhibitor Crizotinib. She was monitored with regular blood complete picture, hepatic and renal function test, and ultrasound abdomen. Her lesions started regressing within one month, and she achieved complete remission after 6 months of treatment.

Objective: Prevalence of aplastic anemia (AA) is high in the Asian population. This study was done to explore the etiology and association of AA with various socioeconomic and environmental factors. Study design and setting: Study included 1324 consecutive AA cases registered at Armed Forces Bone Marrow Transplant Centre Rawalpindi, Pakistan, from March 2001 to August 2016. The study questionnaire was completed through an interview. It included patients' socio-demographic details, personal and family medical history, environmental attributes and clinico-hematological features. Results: The median age of patients was 20 years, 997 were male and 327 female. Distribution of non-severe, severe and very severe AA was 230 (17.4%); 598 (45.2%) and 496 (37.4%), respectively. The majority of patients were from low (n = 761, 57.5%) or middle socioeconomic class (n = 543, 41%). Consanguinity among patients (n = 806, 61%) was slightly higher than the national statistics. History of chemical exposures included fertilizers (n = 116, 8.7%), pesticides (n = 56, 4.2%) and industrial chemicals (n = 37, 2.8%). PNH clone was found in 63 of AA patients. After excluding 298 patients undergoing HSCT and 660 deaths/lost to follow-up, disease evolution was observed in 38(10.4%) patients out of 366 evaluable patients. These included PNH = 18, MDS = 11 and AML = 9. Discussion: Due to lack of funding and adequate human resource at the center, age and sexmatched controls could not be included. Other limitations were a lack of molecular testing to exclude the possibility of inherited bone marrow failure syndromes on a genetic basis. Conclusion: Younger age, male predominance and higher consanguinity point toward genetic factors in AA etiology among the South Asian population.
