In young adult laboratory rats exposed to cold (6 degrees C) the brown adipose tissue undergoes time-dependent increases in cellularity, vascular supply, and total mass. These changes are largely complete after 16 days in the cold and concurrent generally with the development of a thermoregulatory state not greatly dependent upon shivering. Histologically the brown fat changes from a tissue hav...

AIMS Critical factors responsible for the recurrence of keratocystic odontogenic tumor (KCOT) were examined. METHODS The clinicopathological features were retrospectively studied in 74 patients with 75 sporadic KCOTs. From the 75 KCOTs, 23 were examined for the expression of Sonic Hedgehog (SHH), Patched and Smoothened (SMO) by immunohistochemistry. RESULTS Recurrence in multilocular lesion...

A 32-year-old male patient who was HIV positive presented at the Wits Oral Health Centre complaining of a large swelling of the left submandibular region of three years' duration. The swelling was nontender, soft and doughy on palpation and appeared to be crossing the midline. Bilateral submandibular and submental lymphadenopathy was present. Intraorally the lesion caused considerable elevation...

Lymphoepithelial cysts of the pancreas are a type of true cyst that can mimic pseudocysts and cystic neoplasms. They are very rare, non-malignant lesions that are unilocular or multilocular cystic lesions lined predominantly by mature squamous epithelium and surrounded by non-neoplastic lymphoid elements. We, herein, present a patient with a cystic pancreas tumor mimicking a malignant cystic ne...

Little is known about whether bone marrow-derived circulating progenitor cells (BMDCPCs) can transdifferentiate into adipocytes in adipose tissues or play a role in expanding adipocyte number during adipose tissue growth. Using a mouse bone marrow transplantation model, we addressed whether BMDCPCs can transdifferentiate into adipocytes under standard conditions as well as in the settings of di...

OBJECTIVE To describe the imaging features of pelvic solitary plasmacytoma and to correlate them with the pathologic grade. MATERIALS AND METHODS A retrospective study was performed on the imaging features of 10 patients with a histological diagnosis of pelvic solitary plasmacytoma. The imaging studies were assessed for bone expansion, cortical destruction, signal intensity/density of soft ti...

Objective: Thymic cysts are rare mediastinal cystic pathologies and have two subtypes namely unilocular multilocular. This study aims to investigate the clinicopathological characteristics of thymic compare clinical histopathologic features multilocular (MTCs) (UTCs). Patients Methods: Twenty-three patients with diagnosis cyst between 2012 2020 were included. We compared cysts. Results: The mea...

Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinico-radiological and histological types. Apart from the most commonly encountered clinicopathologic models there are few variants, whose biological profile is unknown or not elicited. The reason for lack of understanding is the scarcity of case report published in th...
