“…The cellular origin varies from site to site. In the tongue chondromas, it is felt that the lesion develops either from residual embryonal tissue in an area of fetal cartilage, or from pluripotential mesenchymal cells that undergo metaplasia and differentiate into cartilage as a result of some irritating stimulus (8). In the fallopian tube, Spanta and Lawrence (4) suggested mesenchyme of the myosalpinx or subcoelomic mesenchyme of the tubal serosa as the origin.…”

Extraskeletal chondroma can occur in the hands, feet, head and neck. This tumor usually presents as a small solitary nodule. The histogenesis of the tumor is controversial, but some have suggested a metaplastic origin. Chondroma of the fallopian tube is very rare. There is only one report in English literature. The origin of this tumor can be subcoelomic mesenchyme of the tubal serosa or mesenchyme of the myosalpinx. We describe a case of chondroma arising from the serosal surface of the fallopian tube with a review of literature. A 30-yr-old woman visited hospital due to left adnexal mass. On operating finding, 2 x 3 cm sized nodular mass was noted on the left tubal serosal area. The excised mass showed multilobulated appearance covered with thin fibrous membrane. The cut surface was solid, grayish yellow, and myxoid with a focal gelatinous area. The microscopic finding showed islands and elongated lobules of mature benign cartilage without cytologic atypia.

“…In the head and neck, extraskeletal chondromas are rare, having been described mainly in the tongue [3, 4]. To our knowledge, only one extraskeletal chondroma has been reported in the preauricular region [5].…”

An extraskeletal chondroma is a rare benign cartilaginous tumor that develops in soft tissue. Histologically, it is a lobulated nodule surrounded by a fibrous capsule; the inside consists of mature hyaline cartilage containing a few normal chondrocytes. We present a rare case of extraskeletal chondroma in the preauricular region. A 43-year-old man presented with a 2-cm-diameter right preauricular tumor that had been developing for 1 year. Magnetic resonance imaging showed a solid lobulated tumor in the right preauricular region, which was proximate to the capsule of the right temporomandibular joint (TMJ). This was subsequently resected under general anesthesia. The tumor was not in contact with the TMJ capsule and had not invaded the surrounding tissue, facilitating en bloc excision. Histopathologically, the tumor comprised mainly of hyaline cartilage containing chondrocytes with chondrocytic lacunae and was diagnosed as a chondroma. The postoperative period was uneventful, and there was no evidence of recurrence at the 2-year followup. We describe the clinical characteristics of our case and review the literature, emphasizing the differential diagnosis.

“…The tumour cells probably arise from uncommitted mesenchymal stem cells either by metaplastic or neoplastic processes. Theories about their origin vary, YASUOKA et al suggested that tongue chondromas develop from residual embryonal tissue in an area of fetal cartilage, or from pluripotent mesenchymal cells that undergo metaplasia and differentiate into cartilage as a result of an irritating stimulus 15,48 . In the fallopian tube, the tumour could develop from the mesenchyme of the myosalpinx or subcoelomic mesenchyme of the tubal serosa 38 .Chondromas and cartilaginous tumours have also been studied cytogenetically 6,40 .…”
