Granular Cell Myoblastoma of the Orbit

Unusual Myogenic Tumors Around the Eye

“…The child returned on Aug. 1,1955, with a soft pinkish tissue mass in the area of the inner canthus above the caruncle. Four days later this tumor was excised and a histologie examination showed again a malignant tumor, but this time the diagnosis of a rhabdomyosarcoma could be made (Fig.…”

Granular Cell Tumor (Myoblastoma) of the Eyebrow

“…They generally affect pa tients between the ages of 30 and 50 [ 10,15]. In reviewing the ocular adnexal cases of gran ular cell tumors [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], the age of the patients ranged between 8 and 58 years with a mean age of 37 years, and a median of 38 years. No sex predilection was found.…”

“…In most cases of periocular tumors there was no recurrence after excision of the tumor, but in 2 cases [3,15] the tumor recurred, and a second excision was needed. In one of these cases [3] mitotic figures were described histologically.…”

“…In most cases of periocular tumors there was no recurrence after excision of the tumor, but in 2 cases [3,15] the tumor recurred, and a second excision was needed. In one of these cases [3] mitotic figures were described histologically. In the past the terms alveolar soft-part sarcoma and malignant granular cell myoblastoma were used interchangeably, but alveolar soft-part sarcoma is now usually reserved for a highly malignant tumor with a typical (alveolar) microscopic picture [23],…”

“…These tumors are rare in the eye and ocular adnexa. Nine cases were described in the orbit [3][4][5][6][7][8][9][10][11], 7 cases in the eyelids [5. 12-17], one of them [12] metastatic nodule from the ovaries, 1 case in the palpebral conjunctiva [18], 1 in the caruncle [ 19] and 2 in the lacrimal sac region [3.…”
