The cystic fibroma (fibroma cysticum) has central softening or dilated lymphatic vessels. The myxofibroma (fibroma myxomatodes) is produced by liquefaction of the underlying soft tissue. The cemento-ossifying fibroma is hard and fibrous, most frequently seen in the jaw or mouth, sometimes in connection with a fracture or another type of injury.
Cardiac fibroma is commonly treated through surgical excision procedures. The removal of the cardiac tumor requires open heart surgery. During surgery, the tumor and tissues around it is removed to reduce the risk of the tumor returning. [13] Recovery after surgery is between 4–5 days in the hospital and 6 weeks in total.
Myofibrobastoma, also termed myofibroblastoma of soft tissues, is a mammary-type myofibroblastoma that occurs in non-mammary tissues [15] and may be as much as 10-fold more common than the mammary type. [14] Calcifying aponeurotic fibroma, also termed aponeurotic fibroma [16]
The term fibromatosis refers to a group of soft tissue tumors [1] which have certain characteristics in common, including absence of cytologic and clinical malignant features, a histology consistent with proliferation of well-differentiated fibroblasts, an infiltrative growth pattern, and aggressive clinical behavior with frequent local recurrence.
Gardner fibroma (GF) (also termed Gardner-associated fibroma [1]) is a benign fibroblastic tumor (i.e. a tumor containing fibroblasts, the most common cell type in connective tissue). GF tumors typically develop in the dermis (i.e. layer of skin underneath the epidermis ) and adjacent subcutaneous tissue lying just below the dermis. [ 2 ]

Collagenous fibroma is characterized histopathologically by long, sweeping fascicles of uniformly spindled cells that range in size from moderately to hypercellular. Long, thick-walled arteries exhibiting perivascular stromal edema are seen. [7] Gardner fibroma, nuchal-type fibroma, and desmoid tumor are examples of differential diagnoses. [8]
Approximately 10% of individuals with Gardner's syndrome, a type of FAP with extracolonic features, have desmoid tumors. [ 3 ] The World Health Organization reclassified desmoid tumors (termed desmoid-type fibromatosis) as a specific type of tumor in the category of intermediate (locally aggressive) fibroblastic and myofibroblastic tumors .
