- چکیده انگلیسی: Pseudotumour is a benign inflammatory lesion. Mycobacterial spindle cell pseudotumour (MSP) is a rare pseudotumour. It is a benign proliferation of spindle-shaped histiocytes containing acid-fast mycobacterium, commonly reported in immunocompromised patients. MSP is usually associated with mycobacterium avium complex (MAC). Here, we present the case of a 38-year-old gentleman with acquired immune deficiency syndrome (AIDS) who presented with low-grade fever for 1-month duration. Clinically, he had generalised lymphadenopathy. Chest X-ray showed miliary infiltration in bilateral lung fields. Lymph nodal biopsy showed spindle-shaped histiocytes filled with acid-fast bacilli on Ziehl-Neelsen (ZN) stain, suggestive of MSP. Immunohistochemical (IHC) stains were positive for CD68, S-100 and negative for CD31, which are consistent with MSP. Polymerase chain reaction (PCR) of the biopsy tissue was positive for MTB. Highly active antiretroviral therapy (HAART) was continued and anti-tubercular therapy (ATT) was started. The fever resolved within two weeks and there was a resolution of lymph nodal swelling by 6 weeks. The diagnosis of MSP associated with mycobacterium tuberculosis (MTB) makes our case interesting. It is of utmost importance to differentiate MSP from Kaposi’s sarcoma (KS) and other pseudotumours and to know whether it is of tubercular or non-tubercular origin, as the treatment is entirely different.

- چکیده انگلیسی:
Background: Micro RNAs (miRNAs) are small, noncoding RNA molecules. They can function as either oncogenes or tumor suppressor genes. Single nucleotide polymorphisms (SNP) present in the pre-miRNA region could affect the processing of miRNA and thus alter mature miRNA expression. The studies done so far had shown conflicting results regarding association of two common polymorphisms i.e.hsa-miR-146 rs2910164 and hsa-miR-196a2 rs11614913 with breast cancer. OBJECTIVE: In the study, we examined the hsa-miR-146 rs2910164 and hsa-miR-196a2 rs11614913 SNP association with breast cancer patients in north Indian women. Materials and Methods: This study included 100 breast cancer patients and 100 controls and was done over a period of two years. Genotypes of the hsa-miR-146 (rs2910164 G>C) and hsa-miR-196a2 (rs11614913 C>T) were identified by polymerase chain reaction – restriction length polymorphism (PCR-RFLP) technique in peripheral blood DNA samples. Statistical analysis: We assessed the strength of association of miRNA polymorphisms with breast cancer using Odds ratio (OR) along with 95% confidence intervals. Results: Heterozygous genotypes of hsa-miR-196a2 rs11614913 and combined hsa-miR-146 rs2910164 & hsa-miR-196a2 polymorphism were associated with significantly increased risk of breast cancer (OR-1.7, 95% CI–1.00-3.18) and (OR-1.9, 95% CI-0.85-4.46) respectively. Conclusion: Our study suggests that rs2910164 GC and rs11614913 CT genotypes may contribute to breast cancer susceptibility in north Indian women.- انتشار مقاله: 05-07-1395
