Squamous Cell CarcInoma of Gallbladder: A Case Report.

Although gallbladder cancers are rarely seen, the mortality rates are high. Pure squamous cell cancer, which is one of the most rarely seen cancer types in the gallbladder, originates from the squamous metaplasia which forms following chronic irritation in the mucosa. The majority of cases are generally at the inoperable stage when diagnosed as they have been followed up for long-term cholelithiasis. The case is here presented of a 59-year old female who underwent surgical and medical treatment for a bladder tumour 10 years previously and although gallbladder stones were determined at that time, as she was asymptomatic, surgery was not recommended, then with the progression of time, gallbladder squamous cell carcinoma developed.

Paraganglioma of Carotid Body: A Case Report.

Paraganglioma occur from the paraganglionic stems of the autonomic nervous system. They develop from the carotid body and are known as carotid body tumours. These are sporadic, rare vascular lesions showing genetic transfer. Although they are generally benign and have a slow course, because of invasion to adjacent neurovascular tissues or pressure, early diagnosis and treatment is of importance. Diagnosis is made from a detailed history and physical examination and is confirmed with angiography. The treatment method selected in the majority of cases is surgery. In this paper, the case is presented of a 73-year old female who underwent surgery in our clinic for a diagnosis of carotid body paraganglioma.

Recurrent Eccrine Porocarcinoma: A Case Report.

Eccrine porocarcinoma is a very rarely seen malignant skin tumour which originates from the intra-epithelial section of the eccrine sweat glands. They are generally seen in the elderly and are most often located in the lower extremities. This tumour which has a poor prognosis and displays different biological behaviour, often has a tendency to recurrence and metastasis is seen in the skin and lymph nodes. The basis of treatment is surgical excision and if there is lymph node involvement, regional lymph node dissection must be applied. The case is here presented of a 67-year old patient with eccrine porocarcinoma which developed in the inguinal region and showed recurrence.
