Bilobular calcifying XXXX in soleus muscle: a case report.

@entity1 @entity82 @entity706 @entity5 @entity730 @entity21939 @entity291
INTRODUCTION: Calcifying @entity82 is a rare benign soft-tissue lesion composed of fibrous tissue with abundant hyalinized collagen and dystrophic and often psammomatous @entity730 . The cause of the disease is unclear but, usually, complete resection of the well-circumscribed @entity5 is sufficient to avoid recurrence of the disease. Here, we report an unusual case of this rare @entity5 that presented as two lobulated lesions in the @entity291 muscle. CASE PRESENTATION: The @entity1 was a 17-year-old Japanese @entity1 who noted a hard mass in her left @entity291 . Magnetic resonance imaging revealed two well-demarcated lobular masses in the soleus muscle, and the @entity5 was significantly enhanced by contrast medium. Preoperative differential diagnoses included soft-part @entity5 composed of fibrous tissue. However, making a definite diagnosis was impossible because a lobulated shape is rare for @entity5 . Biopsy demonstrated that the mass was a benign @entity5 composed of collagen-rich, hyalinized fibrosclerotic tissue. We performed marginal resection of the two nodules, including the fibrous tissue that connected them. Immunohistochemistry was positive for @entity21939 and negative for @entity706 kinase-1. These findings were helpful to distinguish calcifying @entity82 from @entity5 . There was no sign of recurrence at 30 months after surgery. CONCLUSION: To the best of our knowledge, this is the first case of bilobular calcifying @entity82 that developed in an extremity. As described in the previous literature, simple excision was sufficient for the treatment of calcifying @entity82 with two lobules.
