“…The etiology of intramuscular lipoma is unknown. Copcu argued that in rare cases they may arise following trauma (Copcu and Sivrioglu, 2003). Mori et al (2004) reported a type-selective fiber atrophy in 70% of infiltrating lipomas examined by immunohistochemical analysis.…”

We describe a rare intramuscular infiltrating lipomatous tumor affecting the superior oblique muscle. A 37-year-old female presented with eyelid swelling, proptosis and motility disturbance. Imaging studies revealed enlargement of the superior oblique muscle with a fat-density infiltrating lesion within its belly. The clinical and radiologic findings suggested a cystic or necrotic lesion. Biopsy showed an infiltrative tumor consisting of adipocytes with included degenerated muscle fibers. Histologic features were consistent with a benign intramuscular lipoma, rather than the more aggressive well-differentiated liposarcoma. A review of the literature found three previously described periorbital cases, two in the eyelid, and one in the anterior orbit. Lipomas are common tumors that usually do not cause functional impairment but are very rare in the orbit. Intramuscular lipoma is a rare subtype that can result in significant morbidity. Enlargement of an extraocular or periorbital muscle with a low-density infiltrating lesion should raise suspicion for this unusual tumor.

“…Since axillary region is one of the most movables of the body, it can be exposed to microtraumas with each movement of the upper limb [8]. In our case it is surgical trauma that has most probably led to recurrence of axillary lipomas into giant axillary lipomas.…”

“…Multiple causative factors have been proposed that include genetic [14] traumatic [15] and metabolic [16] triggers. The genetic theory for lipoma formation proposes that spontaneous karyotypic anomalies lead to chromosomal fusion products which promote proliferation of adipocytes [14].…”

Article HistoryIntroduction-Lipoma is the most common and most widely distributed tumor seen in the body. The most common clinical presentation is a gradually increasing, soft and non-tender mass. These tumours are very rare in hands and if they are present then they are of small size and usually one in number. Herewith we are presenting a case of Palmar Lipomatosis which had a large tumour and 4 small size tumour in same palm. Case report-Herewith we are reporting a case of a 40 years old female, presented with the complaints of multiple swellings in the right palm. She first noticed a small swelling on the thenar aspect of palm about 1½ years back; which was slowly, progressively increasing in size since then. Meanwhile patient also noticed some other swellings in the same palm. Incisions were given over thenar, hypothenar and at the bases of finger. All the tumors were removed en-masse. Biopsy report was fibrolipoma. ConclusionPalmar lipoma is very rare tumour. Palm has very limited space for these tumours to grow but still these tumours can be found in palm. Very limited case reports about the lipoma of hand are present in literature. Here we presented a rare case of palmer lipomatosis which has multiple lipomatous swellings in same plam. They were removed successfully without any residual deformity.
