Signs and symptoms
Spindle cell lipoma is most frequently located in the upper back, shoulder, or posterior neck subcutaneous layer.[3] Nonetheless, reports of it occurring in the mediastinum, hypopharynx, larynx, anterior neck, suprasellar region, esophagus, nasal vestibule, tongue, floor of mouth, vallecula, parotid gland, and breast have been made.[4] The tumor is said to have an average diameter of 4 to 5 cm and is growing slowly. Usually, the tumor is painless and solitary.[3] There have been documented rare instances of numerous lesions, including family occurrences.[5]
Causes
The exact cause of spindle cell lipoma is unknown.[3]
Diagnosis
The diagnosis of spindle cell lipoma is mainly made in conjunction with clinical presentation and after other malignant tumors have been ruled out using cytologic, histologic, and cytogenetic evidence.[6]
According to histology, the lesion is made up of tiny, homogeneous spindle cells and mature adipocytes combined with eosinophilic collagen bundles inside a myxoidstroma. According to immunohistochemical staining, the spindle cells are positive for CD34 but negative for S-100 protein.[3]
