Soft tissue sarcoma is associated with various rare cancers, which includes clear cell sarcoma
, angiosarcoma, alveolar soft-part sarcoma, malignant mesenchymoma, adult fibrosarcoma, clear cell sarcoma
, rhabdomyosarcoma, and kaposi sarcoma.
The differential diagnosis of MNTI includes other small round blue cell tumors of childhood, especially neuroblastoma, Ewing sarcoma, alveolar rhabdomyosarcoma, and lymphoma, in addition to melanogenic tumors, including malignant melanoma and clear cell sarcoma
of soft tissue.
Because of the unusual histologic presentation, which included the presence of clear cells, multinucleated giant cells, and with no epidermal in situ component, the differential diagnosis included clear cell sarcoma
and Spitz nevus.
In broad terms, the differential diagnosis of epithelioid MPNST includes melanoma, clear cell sarcoma
, epithelioid sarcoma and carcinoma.

of the kidney (CCSK) is an uncommon malignant tumor of uncertain histogenesis that occurs most commonly in childhood .
Of 51 nephrectomy specimens, 46/51 was RCC; 5/51 were others which include solitary fibrous tumour, clear cell sarcoma

Liam Debbage, 31, was diagnosed with clear cell sarcoma

Clear cell sarcoma
(CCS) is a rare distinctive soft tissue sarcoma, known to originate from neural crest cells, that has been classified as a variant of melanoma since it was first reported in 1965 .
The most useful tests in reevaluating diagnosis were FISH (for assessing MDM2 amplification status to determine whether differentiated lipomatous tumours or pleomorphic tumours were ALT/WDL or DDL, resp.) and for assessment of EWSR1 gene rearrangement (for diagnosis of a variety of tumours, such as clear cell sarcoma
FNAC of clear cell sarcoma
showed loosely cohesive atypical spindle to oval cells entangled in stroma.
