Chondromas and chondromatosis (a study of 265 cases, 200 with long term follow up).

265 cases of solitary chondroma, multiple chondromas and chondromatosis were analysed. Two hundred cases had a long term follow up of 1-50 years (average ten years). Recurrence after surgical removal is rare. It is exceptional for malignancy to develop in chondromas of the hand. Malignant degeneration (chondrosarcoma, fibrosarcoma, etc.) was found in 12 per cent of the solitary chondromas and in 32 per cent of the multiple chondromas and chondromatosis involving the bones elsewhere than in the hand. The first of these figures is probably excessive, since many of the solitary chondromas elsewhere than in the hand remain asymptomatic and unrecognised; but the second figure is probably too low, since the risk of sarcomatous degeneration remains present throughout the patient's life.

[71 pulmonary hamarto-chondromas].

Seventy-one hamarto-chondromas were operated on at the Centre Chirurgical Marie-Lannelongue from January the 1st 1958 to September the 1st 1975. Pulmonary hamarto-chondroma is always a slowly evolving benign tumour, usually found in patients between 40 and 60, and twice as frequent in males as in females. There are two different kinds. 1) Intraparenchymal hamarto-chondromas, which have a noteworthy clinical latency and in 2 cases out of 3 are situated anteriorly and peripherally. The usual treatment consists of simple enucleation. 2) Endobronchial hamarto-chondromas, on the other hand, have a striking symptomatology of bronchial obstruction. If operated on after some delay, they will cause the destruction of distal parenchyma. Treatment depends on their topography. Segmental resection is often the sole recourse.

Chondroma of the trachea: report of a case and review of the literature.

Chondroma of the trachea is an extremely rare neoplasm. A patient is described who required surgical treatment for this abnormality on three separate occasions over a nineteen-year period. The last two instances represent either local recurrence or new primary growths. The most recent presentation was that of a very large mediastinal mass causing tracheal compression, dysphagia, and superior vena caval obstruction. The clinical and pathological features of chondromas of the tracheobronchial tree are discussed. Because of its recognized potential for local recurrence, a localized chondroma of the trachea is best managed by tracheal resection.

[Bronchopulmonary hamartomas, chondromas, fibromas and myxomas].

The observation of 23 bronchopulmonary hamartomas, 9 chondromas, one fibroma and one myxoma has provided insight into the particularities of these tumors. The group of hamartomas, tumors of "erroneous mixture of tissue", included 20 cases which can be considered a malformation of the entodermal bronchial anlage, and 3 cases which can be regarded as a malformation of the mesenchymal anlage. The first type consists of multiple cleft-like spaces surrounded by ciliated and cuboidal epithelium. There are no alveolar cells. Cartilaginous, fibrous, myxomatous and lipomatous tissue and lymphocytes are also found. The second type consists mainly of undifferentiated mesenchymal cells with tubules, lined by cuboidal epithelial cells or an intestinal type of mucus-secreting epithelium. There may be some immature alveoli, but no ciliated epithelium is found. In contrast to the hamartomas, the chondromas are not derived from a dysontogenetic malformation of the bronchopulmonary tissue but are tumors which develop directly from the bronchial cartilage and are for this reason mainly localized in the endobronchial region. A special form seen in one case is association of pulmonary chondromas, gastric leiomyomas or leiosarcomas and extra-adrenal paraganglioma, though the latter is not always present.

Odontogenic keratocyst associated with an intramandibular chondroma.

The unusual feature of an intramandibular chondroma in association with an odontogenic keratocyst in a 59-year-old man is described. The keratocyst recurred and required two reoperations. The coexistence of an odontogenic keratocyst and a chondroma of the jaw was probably a coincidence of two simultaneous but otherwise unrelated lesions. The possibility that the keratocyst and the chondroma were due to a single developmental disturbance of the region cannot be excluded. No signs of a recurrence were seen at the last follow-up examination four years after the operation.

Radiologic diagnosis of chondroma and chondrosarcoma of the larynx.

The radiographic findings in chondroma and chondrosarcoma of the larynx basically comprise a discreet soft tissue mass on plain lateral and anteroposterior film, a smooth mucosal outline to the lesion, calcification, with either peripheral or central stippling and ossification. Secondary signs are also noted. Definition of these criteria are illustrated in order to apply these findings to the radiographic diagnosis of chondroma and chondrosarcoma of the larynx.

The triad of gastric epithelioid leiomyosarcoma, functioning extra-adrenal paraganglioma, and pulmonary chondroma.

The triad of gastric epithelioid leiomyosarcoma, functioning extra-adrenal paraganglioma, and pulmonary chondroma was found in two young female Mayo Clinic patients, and two of these tumors occurred in another two. Review of the world literature disclosed nine patients who probably had two or more of the three neoplasms. We are also aware of two other patients with two of the three tumors. The association of gastric epitheloid leiomyosarcoma, functioning extra-adrenal paraganglioma, and pulmonary chondroma may well constitute a syndrome because of 1) the improbability of the coincidental occurrence of this triad of tumors, 2) the multicentricity of the tumors in the organs or system affected, and 3) the development of the tumors at a young age. Because two of the components of the triad are potentially lethal, it is important that patients less than 35 years of age who have any one of the three tumors be examined periodically to search for the others.

Bilateral extraosseous chondromas of the hand in a patient with chronic renal failure.

Extraosseous cartilage tumors of the hand are rare. Histologically they can be distinguished from chondrosarcomas. We report a patient with bilateral extraosseous chondromas of the hand with rapid appearance and growth of this unusual tumor during chronic renal failure. The clinical and histological characteristics of these benign tumors are reviewed, and the possible role of the patient's depressed cellular immunity in the appearance of these chondromas is discussed.

Chondroma of the anterior nasal spine.

Chondromas in the head and neck, and particularly in the nasal region, are uncommon. A unique case of a chondroma within the anterior nasal spine has been reported. The asymptomatic lesion was discovered radiographically and mimicked a mesiodens. The tumor consisted of benign-appearing cartilaginous tissue; enucleation has resulted in a apparent cure. A hamartomatous origin has been postulated for this unusual lesion.

[An operated case of clivus chondroma (author's transl)].

A case of clivus chondroma was presented in detail with a review of twenty-four cases reported in Japan. A twenty-eight-year-old house wife was admitted to hospital with complaints of muscle weakness and numbness on the right side of the body. Neurological examination revealed the right hemiparesis and hemihypesthesia. Cranial nerve palsies were also disclosed on the right Vth and the left IXth, Xth and XIth nerves. Craniograms showed a ring-like calcified shadow localized in the clival region without definite bone destruction. Roentgenograms disclosed many well-demarcated radioluscent areas in the phalanges of both hands and feet. The marked separation between the basilar artery and the clivus was demonstrated on vertebal angiograms and pneumoventriculograms. CT scan showed an irregularly shaped low density area localized on the clivus, which turned out to be enhanced following contrast infusion. The tumor was partially removed by the subtemporal approach, and was histologically chondroma. The patient was discharged, gaining adequate muscle strength after operations.

Orbital chondroma rodens in a dog.

A chondroma rodens involving the superficial medial aspect of the right orbit was diagnosed in a 9-year-old dog referred because of chronic unilateral epiphora. Examination revealed several ophthalmic abnormalities attributable to a space-occupying mass in the superficial medial aspect of the orbit. The mass was excised; however, regrowths at the primary site necessitated additional surgical interventions. The dog was given radiation therapy, which provided encouraging results. Subtle histologic differences as well as differing epidemiologic features suggest that chondroma rodens is not analogous to the human entity of juvenile aponeurotic fibroma, to which it has been compared in the past.

[A case of Maffucci's syndrome with intracranial chondroma (author's transl)].

A rare case of Maffucci's syndrome with intracranial chondroma was reported and the literature reviewed. A 16-year-old female high-school student was reffered to our service with 2 month history of diplopia and headache. She had been noticed to have multiple subcutaneous blueish nodules in the lower extremities and multiple body deformities in the four extremities since 6 months old. A biopsy of a skin lesion revealed cavernous hemangioma with calcified thrombi. Another biopsy from the deformed right femur showed it to be enchondroma. Skull series, carotid and vertebral arteriographies, and CT scan revealed a left parasellar mass, which had brought her sensory impairment of the left V1 and the left abducens palsy. The biopsy of the extradural mass in the medial portion of the left middle fossa proved it to be chondroma identical with the right femur lesion. So far as one year postoperative follow-up, she has been doing well with the postoperative sequela of mild left oculomotor paresis, having no evidence of malignant degeneration.

Chondroma of soft parts.

The clinical and pathological features of 104 cases of chondroma of soft parts are presented. The tumor occurred predominately in the third and fourth decades, was slightly more common in male (61%) than in female patients, and affected chiefly the soft tissues of the hand (64%) and feet (20%). The presenting symptom was usually a slowly and insidiously growing mass, occasionally causing tenderness or pain. Nearly always the tumor was well demarcated and lobulated and measured between 1 and 2 cm in greatest diameter. Microscopically, most of the tumors were composed of adult-type hyaline cartilage, undergoing calcification in a large percentage of cases. In addition, histologic variants with giant cell proliferation and chondroblastic activity could be distinguished. Despite the slight cellular pleomorphism and the plump appearance of many cartilage cells in the chondroblastic variants, there was no evidence that these tumors behaved differently from the tumors composed predominately of adult-type hyaline cartilage. Of the 56 patients with follow-up information (median follow-up period, 5.7 years) 44 were alive and well with no evidence of recurrence in the follow-up period. In 10 patients the tumor had recurred once. Multiple recurrences or metastatic lesions were no observed. Two patients died of unrelated cause. Complete local excision appears to be the treatment of choice.

Tenosynovial chondroma of the hand: a case report with a brief review of the literature.

Tumors of hyaline cartilage occurring in the soft tissues of the hands and feet arise by metaplasia from the synovium of tendon sheaths and have a benign clinical evolution. Although recurrences may develop, they show no tendency to metastasize. The majority of these tumors prove to be diagnostic difficulties because of the alarming histologic atypia they display. We report a case of tenosynovial chondroma of the hand and briefly review the salient features of these lesions.
