Macrodystrophia Lipomatosa of the Finger: A Case Report

Introduction: Macrodystrophia lipomatosa is a rare benign condition characterized by a progressive persistent proliferation of the mesenchymal components and elements, with a disproportionate increase in fibro-adipose tissue. It causes a debilitating functional and psychological effect on the patient and his family. Case presentation: A 25-years-old male patient presented complaining of left middle finger swelling which was painless and progressive in size with no restriction of range of motion. Plain X-ray films of the left hand showed a heterogeneous lobulated soft tissue mass on the volar aspect of the middle finger which was confirmed by MRI scan. Surgery was performed by doing a left middle finger soft tissue excision and diagnosis of Macrodystrophia lipomatosa was confirmed by the histopathology report. Patient was on regular follow up in the clinic with no tumour recurrence and an excellent cosmetic as well as functional result with full finger joints range of motion. Conclusion: Macrodystrophia lipomatosa should be suspected with this kind of presentations. Combination of the clinical history and examination with the aid of radiological assays aided in the diagnosis of this extremely rare case and led to the appropriate management by excising this mass and restoring the normal function of the patient’s hand

Fibrocartilaginous dysplasia: What do we know so far?

Fibrocartilaginous dysplasia has been described as a rare variant of fibrous dysplasia. This lesion will appear in imaging as ground glass matrix similar to fibrous dysplasia, but it will also show rings and arcs calcifications. In turn, this can lead to misdiagnosing fibrocartilaginous dysplasia as primary cartilaginous lesion such as enchondroma or chondrosarcoma, neccesating histopathological confirmation. We report a case of fibrocartilaginous dysplasia in a 19 years old male with polyostotic fibrous dysplasia with prior pathologic fracture of the left femur. The patient presented with progressive swelling of the left thigh, imaging was done and showed enlargement of the fibrous dysplasia in the left femur with new rings and arcs matrix mineralization. The lesion was biopsied and microscopic evaluation revealed mainly cartilage islands with fibro-osseous tissue. We also discuss the possible origin of the cartilaginous component in this lesion, and its clinical course
