In 89 preparations of patients with a carcinoma of the prostate and 100 preparations of patients with a hyperplasia of the prostate (adenoma of the neck of the bladder) the appearance of primarily atypical hyperplasias was investigated. In these cases in the carcinoma group in the uniform as well as in the pluriform carcinomas a coincidence of carcinoma and atypical hyperplasia of 55% was found. The coincidence is particularly high in adenocarcinomas and in carcinomas with dominating adenoid part, respectively, i. e. in more mature glandular structures. Among the various histological types of the atypical hyperplasia the microglandular/papillary clear-cellular form is dominating with 82%. In the group of the benign hyperplasia of the prostate gland a coincidence of the atypical hyperplasia of 33% was found. Though this rate, in comparison to other investigators, seems to be relatively high, it is still significantly lower than in the carcinoma. From this follows that the atypical hyperplasia, particularly its severest forms and dysplastic deformations from other hyperplasias (postatrophic hyperplasia, basal cell hyperplasia, atrophy and metaplasia of the prostate) now as ever are suspected that these cases in question are precancerous lesions. For the clinically working urologist the task is derived in such histopathological diagnoses by clinical and bioptical follow-up controls to find an already existing, but still unrecognized, or developing carcinoma of the prostate gland. In no case the diagnosis may cause surplus therapeutic consequences.

B3 breast lesions, classified as lesions of uncertain malignant potential, present a significant diagnostic and therapeutic challenge due to their heterogeneous nature and variable risk of progression to malignancy. These lesions, which include atypical ductal hyperplasia (ADH), papillary lesions (PLs), flat epithelial atypia (FEA), radial scars (RSs), lobular neoplasia (LN), and phyllodes tumors (PTs), occupy a "grey zone" between benign and malignant pathologies, making their management complex and often controversial. This article explores the diagnostic difficulties associated with B3 lesions, focusing on the limitations of current imaging techniques, including mammography, ultrasound, and magnetic resonance imaging (MRI), as well as the challenges in histopathological interpretation.

Background: Keratoacanthoma is a relatively rare skin tumor, with vulvar keratoacanthoma being even more uncommon. Although the majority of keratoacanthomas exhibit a benign course, a subset of cases may show features of malignant potential, such as marginal invasion and recurrence.
Case: An 82-year-old female presented with a rapidly growing exophytic lesion on the left vulva, measuring 1.

Introduction Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder primarily caused by 21-hydroxylase enzyme deficiency, impairing cortisol synthesis and resulting in elevated androgen levels. CAH presents in two classical forms: salt-wasting (SW) and simple virilizing (SV). Although CAH is rare in India, regional variations and the absence of a national newborn screening (NBS) program pose significant challenges to accurate diagnosis.

Pediatric-type follicular lymphoma (PTFL) is an extremely rare B-cell lymphoma that primarily affects children and young adults, typically in individuals under 25 years old, with a median age of 15 years. Here, we report a rare case of PTFL in a 27-year-old adult male who presented with a slow-growing mass near his left ear. Initial CT scans of the neck revealed two oval-shaped, smooth, well-defined, homogeneously enhancing soft tissue density lesions in the superficial lobe of the left parotid gland.
