The final diagnosis was "Sertoli-Leydig Tumor, moderately to poorly-differentiated with retiform
foci and heterologous elements".
Abrupt onset of livedo reticularis may be followed by retiform
purpura, ulcers, nodules, and gangrene.
areas of the tumor showed positivity for pancytokeratin (strong), betacatenin (nuclear and cytoplasmic), calretinin, WT-1 (nuclear staining), PR, CK7 (weak and focal), and inhibin (weak) and negative staining for ER, glypican-3, cyclin-D1, napsin, CK20, D2-40, p53, AFP, CD10, HEPAR-1, and arginase.
Here we describe a patient with ANCA-positive systemic vasculitis, manifested as cutaneous retiform
purpura, leukopenia, and crescentic glomerulonephritis, in whom cocaine adulterated with levamisole was detected in urine.
Microvascular occlusion syndromes typically present with a sometimes palpable, nonblanchable purpura or eschar, frequently with a retiform
During her hospitalization, she was noted to have developed lower extremity skin changes with angulated retiform
purpura of the upper lateral legs and worsening ulcerations with overlying scale crusts of the skin of the lower legs and thighs.
SLCT having retiform
pattern are associated with 20% malignancy rate.
parapsoriasis, or parapsoriasis variegata, is a rare variant of large plaque parapsoriasis that typically presents with a zebralike pattern of atrophic plaques; Dr.
Rare neoplasms have a diffuse pattern of growth that on low power can be vaguely reminiscent on occasion of dysgerminoma because of an alveolar pattern (Figure 8, C; analogous to an issue described recently in testicular tumor pathology), and other less common patterns of Sertoli cell neoplasia include cords, trabecular, pseudopapillary, retiform
, and spindled.
haemangioendothelioma is a rare variant of low-grade angiosarcoma with an indolent clinical behaviour, with predilection for young adults.
Numerous architectural patterns of growth were described, including tubular, ductal, papillary, retiform
, sex cord-like, solid, and sarcomatoid, and these patterns may be seen in various proportions within the same tumor (Figure 13).
