متن کاملHistological diagnosis of cutaneous "warty" carcinoma on a pre-existing HPV lesion.
A middle-aged man with an 8-year history of a fungating tumour mass on his thigh was histologically diagnosed as having an invasive "warty" carcinoma at the location of a pre-existing human papillomavirus (HPV) lesion. The tumour surface had a verruciform appearance with papillae containing fibrovascular cores. Many of the malignant cells displayed changes consistent with koilocytotic atypia. W...
متن کاملThe Gray Zone in Thyroid Nodules: Atypia of Undetermined Significance/Follicular Lesion with Unknown Significance
