So-called hamartoma of the lung-a true neoplasm of fibrous connective tissue of the bronchi [PDF]
Cancer, 1973 A study of 50 so-called hamartomas of the bronchi and lungs, and a review of the literature, revealed clinical and pathologic evidence which was contrary to a developmental origin and supported a neoplastic origin of these lesions. The age of presentation and growth in adults contradicts generally accepted view that they are hamartomas or developmental

Open Medicine, 2016 The fibrous tumors of the pleura are rare primary tumors, accounting for 5% of malignant pleural neoplasms, which generally originate from sub-mesothelial mesenchymal tissue of the visceral pleura. These tumours generally exhibit clinical benign behavior

Epithelioid and Clear Cell Solitary Fibrous Tumors
American Journal of Surgical Pathology, 2022 Solitary fibrous tumors (SFTs) are ubiquitous soft tissue neoplasms known for their protean histology and potentially aggressive behavior. Although most cases are composed of a monotonous proliferation of spindle cells, some tumors show unusual cytologic

Solitary fibrous tumor in bladder wall
International Brazilian Journal of Urology, 2004 The solitary fibrous tumor is a rare mesenchymal tumor, occurring preferentially in pleura, which has recently been described in extrathoracic sites. There are 6 reports on primary solitary fibrous tumor of bladder.

P53 mutations in human adrenocortical neoplasms [PDF]
, 1994 The mechanisms of tumorigenesis of adrenocortical neoplasms have not been elucidated as yet. However, loss of heterozygosity at chromosomal locus 17p has been consistently observed in adrenocortical cancer.

Occurrence of ocular and adnexal neoplasms in canines with special reference to pigmented sebaceous gland epithelioma of eyelids [PDF]
Journal of Veterinary and Animal Sciences, 2023 The eyelid tumours are uncommon in dogs. In the present study, out of 102 ocular and adnexal samples from the dogs examined for a period of 2.5 years, 11 cases (10.78 per cent) were neoplastic in nature. The major location of the neoplasms was eyelids (8/

Clonal Composition of Human Adrenocortical Neoplasms [PDF]
, 1994 The mechanisms of tumorigenesis of adrenocortical neoplasms are still not understood. Tumor formation may be the result of spontaneous transformation of adrenocortical cells by somatic mutations.
