• amphicrine carcinoma
  13 July

  Definition: Amphicrine carcinoma is a distinct type of carcinoma characterized by synchronous exocrine and endocrine differentiation within the same tumor cell.
  Such tumors are exceedingly rare and most commonly recognized in the gastrointestinal tract. In the lung, sporadic descriptions of such lesions exist.
  It is a rare variant of carcinomas showing synchronous exocrine and endocrine differentiation.
  Recognition of this type of tumor is important in terms of tumor classification and (...)

• dysplastic lipoma
  13 July

  Dysplastic lipoma is a distinctive atypical fatty tumor variant that has p53 overexpression and RB1 gene abnormalities and lacks MDM2 gene amplification by FISH.
  These tumors have a strong male predominance and a notable tendency to involve the subcutaneous tissue of the shoulders, upper back and posterior neck.
  Multifocality is frequent (18.9% of patients with follow-up information), and there is a rare association with retinoblastoma.
  This tumor warrants separation from ordinary lipoma (...)
