Obstructive sleep apnea syndrome (OSAS) is a common disorder in childhood with high prevalence in syndromic subjects with craniofacial malformations. Proteus Syndrome (PS) is a rare hamartoneoplastic disorder associated with disproportionate and asymmetric overgrowth of body parts and hypertrophy or malformation of lymphatic tissues, such as palatine tonsils. We report a case of a 12-year-old b...

Choristoma is a tumor-like mass consisting of tissues foreign to the site at which they are located. We report an 18 years old male presenting with persistent tonsillitis. Histological examination demonstrated the unexpected presence of a mature island of hyaline cartilage surrounded by lymphoid hyperplasia.

The adenoids, also known as the Luschka’s tonsil or the nasopharyngeal tonsil, is a mass of lymphoid tissue located posterior to the nasal cavity, in the roof of the nasopharynx. The adenoids along with the palatine and lingual tonsils are an integral part of the Waldeyer’s ring, which represents 3 to 5 % of the entire lymphatic system.

Tuberculosis of the tonsils is by no means a common condition, Mullin (1923), for example, in analysing 400 tonsillectomies found only 4.25 per cent cases of tuberculous tonsils. The present study is based on 2,477 tonsillectomies in the Madras General Hospital. This series covers a period of five years from January 1928 to December 1932. We, however, feel that this investigation is incomplete ...

In the 18th week of the prenatal life large light cells of mesenchymal origin enter the crypt epithelium of the palatine tonsil to start its reticularisation. They are considered precursors of Langerhans cells.

When squamous cell carcinoma (SCC) involves the palatine tonsils, they are generally enlarged and demonstrate intermediate to high signal intensity on T2-weighted MR images and enhance after gadolinium administration. We have identified two patients with SCC of the tonsil where the affected tonsil has low signal intensity on T2-weighted MR images and is smaller than the contralateral normal ton...

OBJECTIVES Mesenchymal stem cells (MSCs) play an important role in the development and growth of tumor cells. However, the effect of human MSCs on the growth of human tumors is not well understood. The purpose of this study is to confirm the growth effect of palatine tonsil-derived MSCs (TD-MSCs) on head and neck squamous cell carcinoma (HNSCC) cell lines and to elucidate the mechanism of their...
