RESUMEN
Background: Lymphoid malignancies are a heterogeneous group of disorders which may be difficult to differentiate from reactive proliferations even after immunohistochemistry. Polymerase chain reaction (PCR) is believed to be a good adjunct tool for diagnosis. Materials and Methods: We examined 24 cases of neoplastic and non-neoplastic lymphoproliferative lesions in this study and evaluated the PCR as an additional tool in the confirmation of the diagnosis. Two different PCR methodologies were evaluated. Results: In the evaluation of the T-cell PCR, it was seen that the correlation using both the commercial kits and the custom-synthesized primers was highly significant at a P value of <0.05. In the evaluation of the B-cell PCR, it was seen that the correlation using both the commercial kits and the custom-synthesized primers was not significant using either method (P > 0.05). Conclusions: Both the methods showed an excellent concordance for T-cell γ gene rearrangements, However, the same was not seen in the B-cell receptor rearrangements. This may be because of the small sample size or the inability of consensus V primers to recognize complementary DNA sequences in all of the V segments.

Gastric glomus tumors are rare neoplasms. We report here a case of gastric glomus tumor in a 25-year-old female who presented with exsanguinating gastrointestinal hemorrhage. Clinically and on gross examination, the tumor was suspected to be a gastrointestinal stromal tumor (GIST). Histopathological and immunohistochemical evaluation revealed it to be a glomus tumor.

BACKGROUND: Chlamydia trachomatis infection in pregnant women can lead to serious maternal/neonatal antenatal or postnatal complications. The aim of this study was to find out the quantum of this problem in antenatal cases of Command Hospital, Kolkata. METHODS: Antibodies to C. trachomatis by ELISA method were tested in sera of 24 pregnant women and 10 nonpregnant controls. RESULTS: Five (20.83%) and 3 (12.5%) were positive and borderline positive for IgM and 1 (4.17%) and 2 (8.33%) were positive and borderline positive respectively for IgG antibodies i.e. an overall positivity of 45.83%. Only 1 (10%) of the controls was positive for IgA antibodies. CONCLUSIONS: This study highlights the importance of performing this simple blood test for detecting C. trachomatis infection in antenatal cases, to treat the infected and prevent the complications.
