Tubuloreticular inclusions in equine connective tissue neoplasms.

Abnormal irregularly branched and anastomosing tubules within cisternae of endoplasmic reticulum were observed by transmission electron microscopy in tumour cells comprising connective tissue neoplasms (sarcoids) from three horses and a mule. These tubuloreticular inclusions were also observed in cultured tumour cells from one of these horses examined, but were not detected in fibroblasts (fibrocytes), epidermis, or vascular endothelial cells in skin biopsy specimens from five clinically healthy horses, nor in one additional equine connective tissue neoplasm.

Mesenchymal, non-meningothelial tumors of the central nervous system.

The spectrum of non-meningothelial mesenchymal tumors that may arise within the central nervous system is presented, based on the current classification of soft tissue tumors. Among malignant types, hemangiopericytoma, rhabdomyosarcoma, mesenchymal chondrosarcoma, and malignant fibrous histiocytoma are the most frequent ones. Rare tumor entities are mentioned. As in soft tissue sarcomas, diagnosis is mainly based on light and electron microscopy, while immunohistochemistry can improve accuracy of diagnosis.

[Blood hypereosinophilias. IV. Symptomatic hypereosinophilias: connective tissue diseases, neoplasms, blood diseases, various causes].

Among the symptomatic hypereosinophilias and apart from pathologies covered in Note III, diseases of the connective tissue, neoplasias, blood diseases and other conditions are also examined. Two connective tissue diseases often accompanied by hypereosinophilias are Churg and Strauss angiitis and eosinophilic fascitis. Churg and Strauss angiitis (of which 2 personal cases are reported) is a systemic vasculitis usually seen in combination with bronchial asthma and haematic eosinophilia. Eosinophilic fascitis is quite rare and poorly understood. Its symptoms include hardening of the skin and eosinophilia and it is difficult to differentiate from progressive systemic sclerosis. The possible reasons why hypereosinophilia sometimes accompanies benign and more often malignant tumours are discussed. The pathogenesis of the hypereosinophilias encountered in diseases of the blood is still controversial. One hypothesis is that hypereosinophilia is an intrinsic symptom of the blood disease, others believe it to be an immunological response. In this context two personal cases are reported as examples: one of hypereosinophilia in a malignant non-Hodgkins lymphoma, the second in an IgG plasmacytoma. Particular attention was paid to the hypereosinophilia that accompanies the rare blood disease known as angioimmunoblastic lymphoadenopathy with dysproteinaemia (LAID) of which a personal case is reported.

Linear nevi, hemihypertrophy, connective tissue hamartomas, and unusual neoplasms in children.

The association of cutaneous nevi, hemihypertrophy, and connective tissue overgrowth has been described in many patients. We report long-term follow-up in two boys with such association who in addition developed testicular neoplasms. One patient also had progressive spinal cord compression as a result of stenosis of the spinal canal, and required amputation of a severely deformed limb. The importance of careful, long-term management in such patients is emphasized.
