Medical Must-See: Chronic haematoma or deadly sarcoma?

Spontaneous chronic expanding haematomas are rare and can closely mimic malignancy on imaging, doctors say.

This Moroccan patient’s benign thigh lesion raised every red flag for sarcoma.

The woman, 55, had no significant history of trauma or disease — just a mass on her left thigh that had been steadily growing for a year.

The mass was firm, fixed to superficial and deep planes and non-tender, with no regional lymphadenopathy.

Lab tests showed her haemoglobin, platelet count, WCC, CRP and coagulation parameters all in normal ranges, ruling out anaemia, infection, inflammatory syndrome and coagulation disorders.
