abstract: introduction: the prevalence of adnexal tumour has been reported to vary between one in eight thousands to 2.3% of pregnancies according to investigational techniques administered. broader use of ultrasonography in pregnancy and the increasing rate of caesarean section (c-section) could be expected to lead to the diagnosis of more adnexal tumours compared to previous studies. aim and ...

ISSN 0001-5555 Most cutaneous adnexal tumours show poor differentiation or differentiate toward only one adnexal structure. Trichoblastomas are benign tumours with hair germ differentiation. We describe here a trichoblastoma-like tumour appearing on the scalp of an elderly woman and propose tha...

Bilateral adnexal torsion is a rare event in children. A high index of suspicion, together with prompt surgical treatment, would help to save the ovaries and preserve its function. We report a case of entangled bilateral adnexal torsion managed successfully via laparoscopy. An 11-year-old premenarchal girl complained of chronic intermittent abdominal pain that worsened over 24 hours. Computed t...

Adnexal masses are common among peri- and post-menopausal women. Although ovarian cancer is a significant cause of mortality in menopausal women, large population-based studies demonstrate that the majority of adnexal masses are benign. Despite this, the appearance of an adnexal mass is a concern for the patient and an insight exercise for physicians. In most cases, an adnexal enlargement is an...

Skin adnexal neoplasms comprise a wide spectrum of benign and malignant tumours that exhibit morphological differentiation towards one or more types of adnexal structures found in normal skin. Most adnexal neoplasms are relatively uncommonly encountered in routine practice, and pathologists can recognise a limited number of frequently encountered tumours. In this review, the first of two, the n...

In recent years, considerable progress has been made in understanding the role of the immune system in tumour progression. However, in canine mammary tumours (CMT), the prognostic value of T-lymphocytes is not established. The aims of the present study were to characterize T-lymphocytic infiltrate in 57 canine mammary tumours (21 benign and 36 malign), by immunohistochemical detection of CD3 an...

AIM To determine (a) the expression of plasma cell related antigens in extranodal marginal zone B cell lymphomas (EMZL) of the ocular adnexa; and (b) the prognostic value of plasmacellular differentiation in these tumours. METHODS A consecutive case series of 136 ocular adnexal EMZL obtained from three ocular pathology centres over 20 years was analysed retrospectively. An extensive immunohis...

A chondroid syringoma or a mixed tumour of skin, is a rare, benign skin adnexal tumour of sweat gland origin, which is most commonly seen in the head and neck region of patients who are in the sixth and seventh decades. These tumours usually present as asymptomatic, slowly growing masses. We are reporting a rare case of a chondroid syringoma of Rt. ala nasi in a 50 years old female. The swellin...

Hidradenocarcinoma is a rare malignant adnexal tumour which arises from the intradermal duct of eccrine sweat glands. The head and neck are the most common sites of hidradenocarcinoma, but rarely it can occur on the extremities. As it is an aggressive tumour, regional lymph nodes and distant viscera are the most common sites of metastasis. Diagnosis is confirmed by histopathology and immunohist...
