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.

A lipoma is a benign tumor made of fat tissue. [1] They are generally soft to the touch, movable, and painless. [1] They usually occur just under the skin, but occasionally may be deeper. [1] Most are less than 5 cm (2.0 in) in size. [2] Common locations include upper back, shoulders, and abdomen. [4] It is possible to have several lipomas. [3]
Between 40 and 80 percent of patients with cancer pain experience neuropathic pain. [1]Brain. Brain tissue itself contains no nociceptors; brain tumors cause pain by pressing on blood vessels or the membrane that encapsulates the brain (the meninges), or indirectly by causing a build-up of fluid that may compress pain-sensitive tissue.

Often, patients can only recognize their prodrome symptoms when they get to the pain phase and look back, Singh says. During a prodrome period, the Mayo Clinic and American Migraine Foundation say ...
Many discrete, encapsulated lipomas form on the trunk and extremities, with relatively few on the head and shoulders. [1] In 1993, a genetic polymorphism within lipomas was localized to chromosome 12q15 , where the HMGIC gene encodes the high-mobility-group protein isoform I-C. [ 2 ] This is one of the most commonly found mutations in solitary ...
[17] [21] Though brain tissue contains no pain sensors, brain tumors can cause pain by pressing on blood vessels or the membrane that encapsulates the brain (the meninges), or indirectly by causing a build-up of fluid that may compress pain-sensitive tissue. [22]
