Basosquamous carcinoma is a type of skin cancer. It is a more aggressive variant of basal cell carcinoma. In addition to the typical features of basal cell carcinoma, basosquamous carcinoma also shows features of another type of skin cancer called squamous cell carcinoma. The tumour starts from specialized basal cells found near the surface of …

A carcinoid tumourlet is a small, non-cancerous growth found in the lungs. It is made up of special cells called neuroendocrine cells. Neuroendocrine cells are normally found throughout the lungs, especially in the airways. When these cells group together and grow slightly more than normal, they can form tiny structures called tumourlets. To be called …

Diffuse alveolar damage (DAD) is a severe type of acute lung injury. It occurs when the tiny air sacs in the lungs, called alveoli, become severely damaged and inflamed. This damage prevents oxygen from moving normally from the lungs into the blood. DAD is closely associated with a condition called acute respiratory distress syndrome (ARDS). …

Alveolar rhabdomyosarcoma is an aggressive type of cancer that develops from immature skeletal muscle cells. Although muscle is found throughout the body, this tumor can arise in places with little or no actual muscle. Alveolar rhabdomyosarcoma is most commonly found in the arms or legs, but it may also occur in the head and neck, …

Background: Embryonal rhabdomyosarcoma (ERMS) is a malignant (cancerous) soft tissue tumour that arises from immature skeletal muscle cells. It is the most common type of rhabdomyosarcoma, accounting for about 60-70% of all cases. This type of cancer predominantly affects children, typically those under the age of 10. Embryonal rhabdomyosarcoma commonly occurs in the head and …

Well differentiated neuroendocrine tumour (NET) of the stomach is a rare type of cancer that starts from neuroendocrine cells in the lining of the stomach. Neuroendocrine cells are specialized cells that receive signals from the nervous system and release hormones into the bloodstream. NETs grow more slowly than other types of stomach cancer and often …

Anaplastic thyroid carcinoma is a rare and very aggressive type of thyroid cancer. Although it starts from the same cells that make up the normal thyroid gland, the tumour cells become so abnormal that they no longer look or behave like typical thyroid cells. For this reason, anaplastic thyroid carcinoma is sometimes called undifferentiated thyroid …
