Cartilaginous choristoma of the tongue with an immunohistochemical study

Intraspinal choristoma in the lumbar region: A case report

RATIONALE

Intraspinal choristoma is a relatively uncommon intervertebral canal tumor. Prior to our reports, only 2 cases of intraspinal choristoma had been reported. Because this disease is not common and looks like a mass of fatty tissue on the magnetic resonance imaging (MRI), intraspinal choristoma can be easily misdiagnosed as teratomas or lipomas (like the case of this article presenting) without a pathology report. So if a lumber intraspinal lesion is discovered in a clinical examination, intraspinal choristoma should be considered as a differential diagnosis. We present a case of intraspinal choristoma that is unlike any other reported case.

PATIENT CONCERNS

A 35-year-old woman with left lower extremity hypoesthesia and burning-like pain in the lumbar region for 1 month visited the local hospital for plain lumbar spine MRI. The patient was diagnosed with a lumbar space-occupying lesion. A second plain lumbar spine MRI scan and a MRI scan with enhancement were performed in our hospital to confirm the presence of a congenital lipoma in the spinal canal. A postoperative biopsy of the lumbar spinal mass indicated that the mass was an intraspinal choristoma located in the spinal canal.

DIAGNOSIS

Intraspinal choristoma.

INTERVENTION

The lesion was surgically removed, and follow-up plain and enhanced MRI images of the patient's lumbar spine were obtained.

OUTCOMES

After surgery, the patient no longer experienced the burning pain in her lumbar region or the left lower extremity hypoesthesia when the patient was discharged. And there was no evidence of recurrence 2 years after the surgery.

LESSONS

The MRI presentation of intraspinal choristoma is similar to intraspinal lipoma. Therefore, a pathological assessment is critical to provide an accurate diagnosis.

Cartilaginous choristoma of tongue - A case report and review

Choristoma (aberrant rest or heterotopic tissue) is defined as a histologically normal tissue proliferation, which is not normally found in the anatomic site of proliferation. Choristoma with a proliferation of chondroid tissue is known as cartilaginous choristoma. Clinically, they present as a painless firm nodule and may produce local dysfunction. They occur most frequently in the tongue and less commonly in other sites, such as buccal mucosa, soft palate and gingiva. We report a 35 years female patient with pedunculated globular growth over the left lateral border of the tongue, resembling papilloma but histopathological analysis of the excised specimen revealed to be cartilaginous choristoma.

Aponeurosis linguae-Myocutaneous or myotendinous junctions of skeletal muscle fibres in the human tongue?

The morphology of the more superficial tissue of the human tongue was investigated and discussed with the clinical appearance of fissures. Three regions could be distinguished according to the presence and shape of the aponeurosis linguae: the central region showed a thick aponeurotic plate with myotendinous muscle fibre insertions. The lateral region showed still an aponeurosis linguae but of reduced thickness and without muscle insertions. The edge-wise and lower region showed no aponeurosis linguae but a fatty subcutis and myocutaneous muscle fibre insertions lacking specific molecules of myotendinous junctions. This system of partially developed exoskeleton seems to underlie but not to be involved in tongue fissures, which are more superficial within the epidermis and dermis.

[Tongue osteocartilaginous choristoma: a case report]

Tongue osteocartilaginous choristoma is the disease that there are well-developed bone and cartilage in the tongue. This article reported a case of tongue osteocartilaginous choristoma in the oral-cavity,which is rare.
