Proliferative Fasciitis in Childhood: A Review of Clinical Data Apropos of a Case

Childhood proliferative fasciitis of the orbit mimicking sarcoma: a case report

Proliferative fasciitis (PF) is a benign fibroblastic reaction with histological and clinical characteristics that overlap with those of malignant soft tissue tumors; thus, it is referred to as a pseudosarcomatous reaction. It continues to be an important cause of diagnostic error and overtreatment. The childhood PF subtype has some distinct histological and immunohistochemical characteristics that make differential diagnosis with malignant tumors even harder, especially with sarcoma. These proliferations generally occur in the lower limbs, and the periorbital region is a rare location of appearance. Here, we describe a case of childhood subtype PF in a 16-year-old girl located in the periorbital area. To the best of our knowledge, this is the first reported case of childhood subtype PF in the periorbital area, and the third case if PF subtypes are not taken into account.

Rare Pseudosarcomatous Lesions Posing Diagnostic Challenges: Histopathologic Examination as a Dominant Tool Preventing Misdiagnosis of Proliferative Fasciitis

Proliferative fasciitis is an extremely rare benign myofibroblastic proliferation that typically presents as a rapidly growing subcutaneous mass. Precise histopathological interpretation is required to obtain a proper diagnosis. Due to a symptomatology overlap, discrimination from soft tissue sarcomas is crucial in the prevention of unnecessary excessive treatment that could be potentially harmful to the patients. Here, we present a rare case of atypical localization of proliferative fasciitis. The lesion was predominantly localized in the groin with the invasion of the scrotum and clinically mimicked soft tissue sarcoma. However, according to a proper histopathologic analysis, the diagnosis of proliferative fasciitis was concluded. With a large number of pseudosarcomatous lesions, there is a rising urge to introduce these rare but benign processes to physicians in order to prevent misdiagnosing patients.

Proliferative fasciitis: A rare cause of disturbances in an adolescent hand

We report a case of hand soft tissue tumor-proliferative fasciitis (PF)-in a 12-year-old patient that presented as a painful lump causing trigger finger. After meticulous diagnostic workup, a surgical excision led to immediate amelioration of symptoms. PF is a rare benign pseudosarcomatous lesion arising typically in the subcutaneous tissue and fascia in adults. It is very uncommon in the hand. To the best of our knowledge, this is the first report of a trigger finger being caused due to this pathology. In this report, the authors review PF lesions on hands, advice careful evaluation of magnetic resonance imaging features, and recommend surgical management.

Proliferative Fasciitis of the Hand in a Nine-Year-Old Girl: A Case Report and Review of the Literature

Proliferative fasciitis (PF) of the hand is a rare condition, which typically occurs in adulthood. To date, only two dozen cases of PF have been reported in children. This benign condition can mimic malignant soft tissue tumors such as soft tissue sarcoma. We present a case of histopathologically confirmed PF of the fifth right finger in a nine-year-old girl, along with the imaging workup. We also provide a review of the previous literature on PF in children.
