Trichoepitheliomas are benign cutaneous neoplasms occurring mostly on the face, which derive from pillous follicles. There are two clinical presentations: a hereditary sex-linked multiple form that usually affects the face, scalp and upper thorax of young adults; and a non-hereditary solitary form that may affect any part of the body (but mostly the face) of adults. The diameter is rarely more ...

An elderly woman presented with dyspnoea secondary to extensive mediastinal invasion by a primary well differentiated liposarcoma of the mediastinum. Five years after partial resection and postoperative radiotherapy (45 Gy) she is alive and well. To our knowledge, long term survival has not previously been reported for a non-encapsulated mediastinal liposarcoma treated by incomplete resection -...

INTRODUCTION The thorax is an area in which distant metastases are frequently observed because it is located on the hematologic and lymphatic pathways (1). Various malignant neoplasms can metastasize to the lung (parenchymal or endobronchial), the hilar-mediastinal lymph nodes, pleura, pericardium, or to the chest wall. The lungs and mediastinum, especially, are the places where other malignanc...

Skin and subcutaneous tissues are the origin of most common neoplasms affecting dogs, accounting for approximately one third of all tumors encountered in the species. Surgical excision is frequently the best chance for a cure; determining factors influencing the success of excision are vital for surgical management of cases. This work examined the shrinkage of skin of various lengths from three...

Solitary Fibrous Tumors (SFTs) are rare primary pleural neoplasms which have recently been reported in extra-thoracic sites. In this report, solitary fibrous tumor arising in an intra-thoracic goiter with no evidence of cervical mass in a 74-year-old obese man who was found to have a large superior mediastinal mass with tracheal deviation on Chest X-Ray is presented.

Transbronchial needle aspiration has recently been adapted for use with the flexible bronchoscope. We studied 108 patients, who had a total of 110 aspirations performed, and diagnosed thoracic cancer in 70 cases. Transbronchial needle aspiration revealed malignant disease in 32 (46%) of these 70 patients. In 12 (17%) patients with cancer this technique provided the sole cytological or histologi...

Primary gastrointestinal (GI) lymphomas constitute less than 8 % per cent of total gut neoplasms. Most of them are Non-Hodgkin’s type of Lymphomas. Among the Extra-nodal tissues Gastro-intestinal tract is the most common site followed by Head and Neck region, Central nervous system, Thorax, Spleen, Adrenal glands, Uro-genital tract, skin and Bone. The stomach is the most common location of GI l...

Objectives. To define the presence of lung metastasis in bitches with malignant mammary neoplasms. Material and methods. Thirty female dogs that were attended at Veterinary Hospital (University of Antioquia, Medellin, Colombia) were selected for the study. At consultation clinical variables and grade of mammary and inguinal lymph node compromise were registered. Laterolateral and ventral-dorsal...

E-mail: [email protected] Various orbital pathological process can cause unilateral proptosis, these include a variety of neoplastic and non-neoplastic lesions. The most common cause of unilateral and bilateral proptosis is G...

background: the aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one ct dataset. materials and methods: for each of six patients with different thorax sizes, two sets of ct images were obtained in single-breath-hold inhale and exhale stages in the supine position. the ct images were then analyzed ...
