According to Tural Selçukbiricik, Günver, Karışmaz, and Serdengecti, “the tumour had an expansive growing pattern and a few pleomorphic, atypical cells, and a rare mitotic activity.”(Tural Selçukbiricik, Günver, Karışmaz, and Serdengecti, 2013) They also completed thoracic, abdominal, and cranial CT scans to determine the state of metastasis. The patient has a routine check-up of every three months to ensure no recurrence occurs and so far, has not had any relapse for two years following her procedure. Malignant chondroid syringoma of the scalp
This 2013 case report by Malik, Saxena, and Kamath investigates the “large, fungating, and ulcerated growth”(Malik, Saxena, and Kamath, 2013) on the scalp of a sixty-one-year-old woman. The tumour was painless and developed gradually over nine months. An initial diagnosis determined the growth to be a squamous cell malignancy of the scalp. The patient was suggested to have a CECT scan of their head. The scan revealed dural invasion and a surgical excision with primary closure was performed. The histopathology findings revealed:“small groups as well as scattered pleomorphic epithelial cells having hyperchromatic nuclei and scanty cytoplasm with one to two mitotic figures of high power field, surrounded by abundant basophilic chondromyxoid stroma, diagnostic of malignant CS.”The woman died two days after her operation after yielding a “high-grade fever and altered sensorium.”(Malik, Saxena, and Kamath, 2013)

Multifocal and recurrent malignant chondroid syringoma
This report follows the development of MCS on a sixty-four-year-old male patient. The masses were described as skin lesions that had developed in a nodular fashion on the patients right arm.
The findings were as follows.“The surgical specimen showed a lobular proliferation of tumour cells with glandular differentiation associated with a few mitotic cells, embedded in a mucinous stroma. Immunohistochemistry showed that the majority of tumour cells were positive for PAS diastase, toluidine blue, cytokeratins (CAM5.2, CK7), S-100 protein and GCDFP-15.”Although some abnormal tumours cells were present, the recorded findings the man was diagnosed with chondroid syringoma. An ultrasound and radiography were performed and revealed no indication of metastasis. However, in 2008, the man observed inflammation in his right groin area. Another ultrasound revealed a new mass also measuring 30 mm x 30mm, which was then excised. Examination of this new tumour revealed more abnormal tumour cells compared to the first nodule of the sole of the foot. The original diagnosis was thus re-examined to be consisting of malignant chondroid syringoma cells. The patient was then treated with radiation. After eighteen months he presented no evidence of recurrence or further distant metastasis. History
Hirsch and Helwig gave malignant chondroid syringoma its name in 1961 in ‘Chondroid Syringoma: Mixed Tumour of Skin, Salivary Gland Type.’ "Atypical mixed tumours of the skin,"(Hirsch and Helwig, 1961) their term for tumours characterised by "histological stigma of malignancy, local invasion, and satellite tumour nodules without proven metastases" is employed even now. As of 2011, only 43 cases have been reported. Terminology
Malignant mixed tumours also go by other names including: "malignant mixed tumour of skin, cutaneous malignant mixed tumour, metastasising chondroid syringoma, and aggressive chondroid syringoma."
