Fibromas are composed of well-differentiated subcutaneous connective tissue and commonly occur in adults aged 40-50. The tumor grows slowly and typically stops enlarging after reaching a certain size. As a benign tumor, it rarely undergoes malignant transformation, with surgical excision being the primary treatment.

1. The mass grows slowly and usually has no other symptoms. 2. The skin over the tumor appears normal, and a smooth, movable, round subcutaneous mass can be palpated. It is non-tender, well-defined, and firm in texture.

Tumor resection.

Fibromas are mostly benign tumors, and complete resection generally prevents recurrence. Clinically, to differentiate them from other diseases, surgical resection is usually recommended, along with histopathological examination. Fibromas in the subcutaneous tissue of the posterior midline of the neck can be palpated when the head is tilted backward but not when it is tilted forward (due to tension in the posterior cervical fascia covering it). They are more common in the elderly and usually do not require surgery. Additionally, some muscle conditions, such as the hard nodules in the sternocleidomastoid muscle in pediatric torticollis, rectus abdominis fibromatosis in women, and sclerosing myositis, may also present as palpable subcutaneous masses. However, these masses do not originate from subcutaneous connective tissue. The main distinguishing feature from fibromas is that these masses are often connected to the muscle (which can be identified through palpation).

Cure: Complete tumor resection.
