Simultaneous presence of two hematological malignancies: chronic lymphocytic leukemia and myelofibrosis in a patient.

Coexistence of chronic lymphocytic leukemia (CLL) with myelofibrosis is a rare association with only isolated case reports in the literature. We report an unusual case of CLL in which the cause of anemia was coexistent myelofibrosis. In a case of CLL presenting with refractory anemia, besides common causes like autoimmune hemolytic anemia and marrow infiltration, other causes like myelofibrosis should be searched for.

Patterns of infections among blood donors in a tertiary care centre: a retrospective study.

BACKGROUND: Transfusion-transmitted infections continue to be a threat to safe transfusion practices. We analysed the prevalence and patterns of co-infections among voluntary and replacement donors. METHODS: Blood donations collected over a 5-year period were studied for the type of donation (voluntary or replacement), number of seroreactive cases and the number, type and distribution of co-infections. RESULTS: Of the 42 439 units of blood collected over a 5-year period, 19 118 (45%) were from voluntary and 23 321 (55%) from replacement donors. There were 1603 seroreactive cases (3.8%). These included 250 with HIV (0.6%), 734 with hepatitis B surface antigen (HBsAg; 1.7%), 337 with hepatitis C virus (HCV; 0.8%) and 282 (0.7%) with VDRL (Venereal Diseases Research Laboratory) reactivity. Twenty-three (0.05%) of these had > or = 2 seroreactive infections; 20 of these were in replacement donors and only 3 in voluntary donors and the difference was statistically significant (p < 0.005). Among HIV seropositive donors, there were 4 seroreactive for syphilis and 5 for HBsAg. Among HIV seronegative donors, 5 were seroreactive for HBsAg and VDRL, 4 for HCV and VDRL, and 2 for HBsAg and HCV. One person was seroreactive for HIV, HBsAg and VDRL. The multiple infection rate showed a decreasing trend over the years. CONCLUSION: Multiple infections pose a small but definite risk to the recipients of blood products. Voluntary donations are safer as compared with replacement ones and need to be encouraged.

Clinico-pathological spectrum of gallbladder disease in children.

AIM: Because of wide variation in clinico-pathological spectrum of gallbladder disease in children the world over, the data of gallbladder disease from this stone belt of India were analysed. METHODS: Children who underwent cholecystectomy over a period of 8 years January 2002-December 2009 were reviewed. RESULTS: Out of 7076 cholecystectomies, 56 (0.79%) were in children. Thirty-nine (69.6%) children were 11-16 years of age. Thirty-seven (66.07%) children were girls and nineteen (33.9%) were boys. In 12 (21.4%) children, cholecystitis was acalculus. Five (8.9%) children had associated haemolytic disease and 4 (7.1%) children had congenital anomaly in the form of choledochal cyst. Ultrasound findings were available in 44 cases and showed cholelithiasis in 36 cases. Twenty-two (39.3%) children had mixed cholelithiasis, 8 (14.2%) pigment cholelithiasis, 10 (17.8%) combined cholelithiasis and 4 (7.1%) patients had small concretions. Microscopically, changes of chronic cholecystitis were seen in 98.2% while 1.7% showed acute on chronic cholecystitis. There was single unusual case of cysticercus in the wall of the gallbladder. CONCLUSIONS: The frequency of gallstone disease is 0.79%. Nonhaemolytic type of cholelithiasis is more common than haemolytic type in this region. Presence of cysticercus in the gallbladder wall in one case was an unexpected finding.

Role of fine-needle aspiration cytology in tuberculosis of bone.

This study was designed to evaluate the role of fine-needle aspiration cytology (FNAC) in diagnosis of skeletal tuberculosis (TB). In this retrospective study, 20 cases were retrieved over a 10-year period in which a cytologic diagnosis of osseous TB was rendered. The aspirations were performed with a 22-gauge needle attached on a 20-ml syringe after taking into consideration the radiological findings. The cytologic findings were subdivided into the following categories--epithelioid cell granulomas with necrosis, epithelioid cell granulomas without necrosis, and necrosis only. These cases were either with or without AFB positivity. The smears showed epithelioid cell granulomas in 23 cases (85.2%), multinucleate and Langhans' giant cells in 15 cases (55.6%), and inflammatory cells were noted in the background in 15 cases (55.6%). AFB was positive in six cases (22.7%). FNA provides a simple and safe outpatient procedure for the diagnosis of osseous TB and obviates the need of an open biopsy.

Fine needle aspiration in the diagnosis of subcutaneous cysticercosis.

Human cysticercosis commonly manifests as subcutaneous and intramuscular nodules. The current study highlights the role of fine needle aspiration cytology (FNAC) in the diagnosis of subcutaneous cysticercosis. One hundred and twenty two patients with subcutaneous swellings, diagnosed as cysticercus or suspicious of parasitic inflammation on FNAC, were included in the present study. The relevant clinical data, cytomorphological findings, and histopathological findings, wherever available were evaluated. In 57 cases, a definite evidence of cysticercus was obtained in the form of fragments of parasite bladder wall, hooklets, or intact larva. Out of these, biopsy correlation was available in 10 cases, eight of which failed to reveal any parasite. In 65 cases, larval fragments could not be identified on aspirates, and the diagnosis of parasitic inflammation was suggested on the basis of other cytomorphological findings, which are discussed. In 22 of these cases, a biopsy correlation was available, which revealed definite parasitic elements in six cases and the remaining 16 cases were reported as suggestive of parasitic cysts. Thus, to conclude, FNAC is a reliable and cost effective procedure for the diagnosis of subcutaneous parasitic nodules. It obviates the need for a subsequent histopathological examination, as the parasite may not be demonstrated even on biopsy specimens.

A comparative analysis of core needle biopsy and fine-needle aspiration cytology in the evaluation of palpable and mammographically detected suspicious breast lesions.

The present study was undertaken to compare the efficacy of needle core biopsy (NCB) of the breast with fine-needle aspiration cytology (FNAC) in breast lesions (palpable and non-palpable) in the Indian set-up, along with the assessment of tumor grading with both the techniques. Fifty patients with suspicious breast lesions were subjected to simultaneous FNAC and ultrasound-guided NCB following an initial mammographic evaluation. Cases were categorized into benign, benign with atypia, suspicious and malignant groups. In cases of infiltrating duct carcinomas, grading was performed on cytological smears as well as on NCB specimens. Both the techniques were compared, and findings were correlated with radiological and excision findings. Out of 50 cases, 18 were found to be benign and 32 malignant on final pathological diagnosis. Maximum number of patients with benign diagnosis was in the fourth decade (42.11%) and malignant diagnosis in the fourth as well as fifth decade (35.48% each). Sensitivity and specificity of mammography for the diagnosis of malignancy was 84.37% and 83.33%, respectively. Sensitivity and specificity of FNAC for malignant diagnosis was 78.15% and 94.44%, respectively, and of NCB was 96.5% and 100%, respectively. But NCB had a slightly higher specimen inadequacy rate (8%). NCB improved diagnostic categorization over FNAC by 18%. Tumor grading in cases of IDC showed high concordance rate between NCB and subsequent excision biopsy (94.44%) but low concordance rate between NCB and FNAC (59.1%). NCB is superior to FNAC in the diagnosis of breast lesions in terms of sensitivity, specificity, correct histological categorization of the lesions as well as tumor grading.
