Abstract T-cell lymphomas are rare neoplasms that have complex pathology. The multiparameter approach has been recommended by World Health Organization (WHO) for the classification of taking into account morphology, immunophenotype, genetics, and clinical features. This also includes division established on possible cell-of-origin (COO) from T regulatory or T-follicular helper (TFH) cells. rece...

BACKGROUND There are inter-observer disagreements between papillary thyroid carcinoma (PTC) with other follicular lesions of thyroid in aspect of diagnosis. CD56 is present on follicular epithelial cells of the normal thyroid. We evaluated the diagnostic value of CD56 expression in PTC, follicular thyroid lesions, and follicular thyroid neoplasms. MATERIALS AND METHODS Seventy-three cases dia...

oocyte maturation and embryo development are controlled by intra-ovarian factors such as steroid hormones. progesterone (p4) exists in the follicular fluid that contributes to normal mammalian ovarian function and has several critical functions during embryo development and implantation, including endometrial receptivity, embryonic survival during gestation and transformation of the endometrial...

Thyroid is a H-shaped gland localised in front of trachea at the base of the neck, whose main functions are the synthesis, the storage and the secretion of thyroid hormones under the control of the hypothalamic–pituitary axis. Thyroid is comprised of spherical follicles filled with colloid that are lined by cuboidal/flat epithelial cells denoted follicular cells (or thyrocytes). The other hormo...

Introduction. Primary cutaneous CD4+ lymphoproliferative disorder of small and medium cells (PC T-LPD small/medium cell) is a new entity identified in the WHO classification published 2017. The aim research was to characterize morphological immunohistochemical features PC cell. Materials methods. study examined 28 skin biopsies from 13 males 15 females with cell using histological Results. We d...

Follicular dendritic cells (FDC) are non-lymphoid, non-phagocytic, accessory immune cells, crucial for antigen presentation and regulation of the reactions in germinal centers. Sarcoma arising from FDC is very rare it has low-to-intermediate malignant potential. Histopathological examination play a critical role diagnosis disease but difficult cases immunohistochemistry great facilitates misint...
