Chondroid syringomas of the eyelid: two cases.

PURPOSE: We report two new cases of chondroid syringoma (CS) of the eyelid. Until 1961, this entity was known as pleomorphic adenoma or benign mixed tumour of the skin of salivary glands type. This tumour occurs most commonly in the head and neck regions. CASE REPORTS: We describe two cases of CS with rapid growth, in the upper right eyelid, with no relation with the palpebral lobe of the lacrimal gland. RESULTS. Treatment consists of wide local surgical excision with its capsule, in its entirety. CONCLUSIONS: These tumours of the ocular adnexa are exceedingly rare. Malignant transformation is possible.

Primary cutaneous adenoid cystic carcinoma of the eyelid.

PURPOSE: To report a case of primary cutaneous adenoid cystic carcinoma involving the eyelid. METHODS: We examined a 70-year-old woman with an 18-month history of a gradually enlarging, blue-colored mass in the medial third of the right upper eyelid. Excisional biopsy and additional resection of the medially infiltrated margin resulted in tumor-free edges. Superior cervical and orbital evaluations were performed. RESULTS: Histopathologic evaluation revealed a primary cutaneous adenoid cystic carcinoma. No gland pathology was documented. No tumor recurrence has been noted. CONCLUSION: Primary cutaneous adenoid cystic carcinoma, an uncommon tumor of the skin, should be added to the differential diagnosis of eyelid tumors.

Juvenile xanthogranuloma of the orbit in an adult.

We present a case of juvenile xanthogranuloma (JXG) with unilateral involvement of the orbit and eyelid and proptosis, histologically confirmed in a 32-year-old man with a 1-year history of a pansinusitis and dacryoadenitis with rhinitis. Nine months later an infiltration of the anterior upper part of the right orbit and right eyelid appeared. Computed tomography scan and magnetic resonance imaging studies confirmed the presence of pansinusitis and infiltration. The patient underwent a blepharoplasty and excision of the infiltrated tissues of the orbit, eyelid, and levator muscle. Hematoxylin-eosin and immunohistochemical studies revealed features consistent with a diagnosis of JXG (Touton giant cells). JXG, a non-Langerhans'-type benign proliferation, is a rare condition in adulthood.

Primary angioleiomyoma of the iliac bone: clinical pathological study of one case with flow cytometric DNA content and S-phase fraction analysis.

We report on a primary angioleiomyoma of the right iliac bone in a 28-year-old woman. To our knowledge this is the 16th reported case of a primary leiomyoma of bone, the 9th reported primary osseous angioleiomyoma and the first description of a primary angioleiomyoma located in the iliac bone. The problems of differentiating primary leiomyoma of bone from primary or metastatic leiomyosarcoma of bone are stressed. A literature review of primary leiomyomas of bone is presented.

Pathology of a new toxic syndrome caused by ingestion of adulterated oil in Spain.

The Toxic Syndrome (TS) caused by ingestion of adulterated rapeseed oil in Spain is a new disease of multisystemic character whose aetiology and pathogenesis remains unknown. The most prominent pathological feature is a peculiar non-necrotizing vasculitis, that affects mainly the intima and involves vessels of every type and size in practically every organ. The TS begins with an acute clinical picture with pleuropneumopathy, fever, headaches, exanthems and eosinophilia. In these early clinical phases the main pathological findings were observed in the lungs and consisted of intense pulmonary interstitial oedema with scanty inflammatory mononuclear infiltrates. Ultrastructural study revealed hydropic degeneration of pneumocytes types I and II with desquamation of type I. The patients in this phase died of respiratory failure, later deaths were due to thromboembolic complications. Later still the patients developed a neuromuscular syndrome, sclerodermiform skin lesions and severe weight loss and died predominantly of infectious complications and respiratory failure. The anatomopathological picture in the peripheral nerves was that of inflammatory neuropathy with a lymphocytic perineuritis that led to perineural fibrosis with secondary axonal degeneration. The muscle presented an interstitial inflammatory myopathy at first followed by a neurogenic muscular atrophy. The skin lesions in the late phases consisted in dermal or dermal and subdermal fibrosclerosis, with vasculitis of the small arteries in the lower dermis. The salivary glands and pancreas showed vasculitis and interstitial inflammation which progressed to interstitial fibrosis and parenchymal atrophy.
