Assessment of rhesus and kell blood group antigens, phenotypes, and their allelic frequencies in North Indian blood donors.

Background: Prevalence of rhesus (Rh) and Kell antigens in a population vary with race, ethnicity, and geographical location. With advances in immunohematology, non-D antigens, and their corresponding antibodies are increasingly being found to be culprits for alloimmunization.

Materials And Methods: Assessment of the phenotype of Rh and Kell blood group antigen in the healthy donor population from North India was done, and estimation of the frequencies of these alleles in our population was performed.

Xantogranulomatous Salpingo Oophritis, Lessons Learnt: Report of Two Cases With Unusual Presentation.

Xanthogranulomatous inflammation is a rare form of chronic inflammatory response consisting of macrophages, lymphocytes, plasma cells and neutrophils too. Due to its locally destructive nature and mass forming capacity as a result of adhesions, this type of inflammation may mimic malignancy or tuberculosis both clinically and radiologically. We present a report of two such cases, one mimicking tuberculosis and the other mimicking malignancy clinically.

Case of chondroid syringoma mimicking a nodular hidradenoma: A diagnostic pitfall on cytopathology.

Limited literature is available on the use of fine needle aspiration (FNA) for skin tumors. Awareness of cytological features of these lesions is important to prevent misdiagnosis. A 45-year-old male, presented with slowly growing swelling over the thigh since 4 years.

Myxopapillary ependymoma: Lesser known cytomorphologic features.

Myxopapillary ependymoma (MPE) is a rare and distinctive tumor which occurs in the sacrococcygeal area of young adults and children, often intradural in location. Histopathologic features have been well-described in the literature whereas cytological findings have been sporadically reported by various authors mainly as case reports. We report the features of a primary sacrococcygeal MPE on aspirate cytology in a 45-year-old female.

Tubulopapillary hidradenoma: A rare case with cytohistopathological correlation.

Tubulopapillary hidradenoma is a rare adnexal neoplasm with only a few cases reported in literature. The tumor shows a female predominance with a wide age range and presents as a well-defined, non-tender nodule most often located on the scalp. Review of the literature yielded no fine-needle aspiration reports of the cytological features of the tumor.

Unusual multicentric angiomyolipoma of knee joint and soft tissue foot.

To report unusual occurrence of angiomyolipoma at intraarticular location with another lesion in the same side foot. A 12-year-old girl was referred to us after initial inconclusive work-up done elsewhere for swelling of left knee joint. There was a 15 × 12 cm swelling in the knee joint partially encasing patella while also a similar hourglass shaped swelling measuring 9 × 4 cm was noted in the same side foot.

Increased hematogones in an infant with bicytopenia and leucocytosis:a case report.

Hematogones are the normal bone marrow constituents of bone marrow in children and their number decreases with age. As hematogones can resemble malignant lymphoblasts by their morphologic features and by expression of an immature B-cell phenotype, an accurate distinction of hematogone-rich lymphoid regeneration from leukemic lymphoblasts is critical for patient care. The increased number of hematogones had been reported in the bone marrow of children recovering from chemotherapy, aplastic conditions, other forms of bone marrow injury, infections like Cytomegalovirus, HIV and immune thrombocytopenia disorders.
