“…CM can be diagnosed on radiographs because of its characteristic peripheral calcification and central liquefaction. 8 , 9 Diagnostic biopsy is generally avoided owing to a high risk of infection (~30%). 7 The general consensus is that asymptomatic CM should be conservatively managed, and it can be considered a “do not touch” lesion.…”

Summary: Calcific myonecrosis (CM) is a rare condition in which a large calcified mass develops after trauma. Generally, CM occurs in a lower extremity, and there have been no reports of its occurrence in the upper arm. We report 2 cases of infected CM, including a rare case of CM occurrence in the arm and a typical case in the leg. Case 1: An 84-year-old woman presented with a draining sinus and a large calcified mass in the arm and axillary region. The mass involved the neurovascular bundle; thus, complete resection was impossible. We performed surgical debridement and postoperative negative-pressure wound therapy with instillation and dwell. Case 2: A 43-year-old man presented with a large calcified mass in the right leg and 2 draining sinuses. After surgical debridement, negative-pressure wound therapy was initiated. However, the wound became infected, and we performed additional debridement, followed by a split thickness skin grafting. The infection was controlled in both patients, although complete resection was not feasible. Complete resection is generally considered the optimum treatment for infected CM, but it is difficult to achieve in some patients. Negative-pressure wound therapy with instillation and dwell appears as a good option for postoperative management if complete resection of infected CM cannot be achieved.

“…To date, only a few cases of liquefaction and calcification within muscle mass have been documented. 11 Recurrent hemorrhage within necrosed and fibrotic muscle tissue is another possibility for the development of this condition, but the actual pathophysiologic process is still unknown. 12 Calcific myonecrosis is a condition that affects people between the ages of 17 and 87, with the majority of cases occurring in the sixth decade of life, according to existing literature.…”

“…2 Calcific myonecrosis, like myositis ossificans, soft tissue sarcomas, diabetic myonecrosis, calcified soft-tissue mass, hematoma, parosteal osteosarcoma, and tumoral calcinosis, poses a diagnostic quandary. 11,13 The majority of these cases have a documented history of prior trauma as the primary contributing factor, with a latent period of years preceding the onset of this slowly growing mass. The majority of the time, laboratory results are within normal ranges.…”

CASE REPORTthe swelling was multilobulated, fluctuant, and tender, measuring 5 × 2 cm on the right leg's mid-anterolateral aspect (Fig. 1).Neurological examination revealed weak dorsiflexion of the right ankle and eversion of the right foot. The radiograph of the right leg exhibited a homogenous radiopaque lesion over the lateral aspect (Figs 2A and B). MRI is suggestive of myositis ossificans lesion restricted to the lateral and anterior compartment of the right leg with no hypervascularity (Figs 2C and D). Blood tests for liver function, serum calcium, phosphorus, and alkaline phosphatase were all normal. A nerve conduction test revealed a decrease in the conduction velocity of the right superficial and deep peroneal nerves. Tru-cut biopsy results suggested myositis ossificans. An excision biopsy was performed under spinal anesthesia with softtissue tumor and myositis ossificans as differential diagnoses in mind. The pus was extracted and sent for histopathological 1,

“…On average, CM symptoms manifest 37 years after the initial injury [3] . History of trauma and radiologic features aid physicians to differentiate CM from neoplasia [1] , [2] , [4] , [5] . Failure to recognize this lesion prompts a biopsy, occasionally with devastating results.…”
