The third pattern was also uncommonly seen, characterized as a rhabdoid
pattern (Figure 2D).
F, High-grade clear cell renal cell carcinoma with epithelioid and rhabdoid
cells (hematoxylin-eosin, original magnifications X40 [A], X100 [B and C], and X200 [D through F]).
1 case of Wilms' with teratoid features and one case with rhabdoid
elements were observed in the study.
Dumbbell-shaped atypical teratoid rhabdoid
tumor in the cervical spine mimicking schwannoma.
The second component, the mural nodules, was composed of nodules of pleomorphic and rhabdoid
cells with large eosinophilic cytoplasm, remarkably enlarged nuclei, and prominent nucleoli.
The differential diagnosis of lesions presenting with cutaneous involvement (ordered most to least common) include: leukemia, Langerhans cell histiocytosis, neuroblastoma, rhabdoid
tumor, rhabdomyosarcoma, primitive neuroectodermal tumor, choriocarcinoma, and adrenocortical carcinoma.
Though not part of tumor staging, sarcomatoid change has been incorporated into the International Society of Urologic Pathology's grading system, in which tumors exhibiting rhabdoid
or sarcomatoid features are placed in grade 4 alongside tumors with marked nuclear pleomorphism.
In a cruel twist, Alfie was just 18-months-old when doctors told the family in September that his brain cancer, a type called atypical teratoid rhabdoid
, was terminal.
The morphology and immunophenotype provided no support for a reactive process, melanoma, lymphoma, carcinoma, epithelioid sarcoma, epithelioid malignant peripheral nerve sheath tumor, rhabdoid
tumor, or alveolar soft part sarcoma.
Consistently, recent studies have demonstrated that childhood cancers such as medulloblastomas, neuroblastomas, and rhabdoid
tumors have very few recurrently mutated genes.
