In addition, cryoglobulinemia can induce a thrombotic vasculopathy, and the first clinical lesion is usually a stellar or retiform
purpura, which evolves into necrosis.
(54) Morphologically, mesonephric carcinoma is characterized by heterogeneous architecture, with various patterns of growth that include glandular/tubular, papillary, retiform
, sex cord-like, solid, and spindled/sarcomatoid (Figure 6, A and B).
Histological analysis, Figures 3 and 4, indicated a predominantly poorly differentiated Sertoli-Leydig cell tumour, retiform
pattern, with heterologous mucinous elements.
Here, we report a case of a Sertoli-Leydig cell tumor with both heterologous and retiform
elements in which only heterologous components were sampled during intraoperative consultation.
The patient was given a diagnosis of levamisole-induced cutaneous vasculopathy based on her history of cocaine use; the typical, painful palpable purpura with angulated borders and a necrotic center (retiform
purpura); and positive immunologic markers.
More recently, heterologous and retiform
differentiation has been described.
There are five histological subtypes of SLCT as follows: well differentiated, intermediate differentiation, poorly differentiated, retiform
, and heterologous or mixed [3-5].
The pituitary gland and its stalk attached to the 3rd ventricle floor were described; like Herophilus, he wrongly placed a retiform
plexus at the base of the human brain.
Its appearance was that of an accumulation of particles resembling white sand surrounded by a network of thin bones (retiform
One patient presented with petechiae, one with simple ecchymoses, and one with noninflammatory retiform
