A case of myositis ossificans traumatica has been reported. Clinical, histopathologic, and roentgenographic entities have been referred to. An up-to-date review of the literature on this disorder has been presented.

Disseminated candidiasis was clinically diagnosed by muscle and skin biopsies in two patients with hematologic malignancies. One patient with acute promyelocytic leukemia presented with skin lesions as the sole manifestation of disseminated candidiasis. The other patient had leukemic reticuloendotheliosis and developed fever, severe myalgias, and maculopapular rash while receiving corticosteroid therapy; this patient is the first to have antemortem documentation of candida myositis as the initial manifestation of disseminated candidiasis. These two case reports serve to emphasize the importance of careful observation and early biopsy of skin and muscle to establish the diagnosis and permit early institution of therapy.

A primary malignant bone disease can generally be suspected on the basis of x-ray findings and may be even highly probable if several signs of malignancy are seen on one and the same film. Such changes include bone lesions larger than 6 cm on the first film with blurred outlines, showing patterns of destruction resembling moth-eaten textiles, the covering periosteum revealing spicula or Codman's triangles. Rapidly growing tumours can break cortex components from the continuous layer and shift them outwards. Roentgenological case controls are useless and must be replaced by a sample excision, since x-ray malignancy signs have no absolute value as decisive criteria in view of the fact that they are seen, inter alia, also in osteomyelitis, myositis ossificans and callus formations.

Focal myositis, a benign inflammatory pseudotumor, is a relatively newly defined clinicopathologic entity which arises as a rapidly enlarging swelling within an isolated skeletal muscle. It occurs most often in the lower extremity, and we are reporting what we believe to be the first cases of perioral involvement. There is no apparent age or sex preference. Focal myositis must be differentiated from neoplasm, nodular pseudosarcomatous fascilitis, proliferative myositis, myositis ossificans, polymyositis, and, in the oral region, salivary gland lesions and hypertrophic branchial myopathy. No lesions have recurred.

We have observed two cases of staphylococcal myositis in patients with acute lymphocytic leukemia which are distinguished from previously reported cases by a history of cutaneous vasculitis overlying the area of subsequent infection.

Five children with Sharp syndrome are described presenting a non-erosive polyarthritis, hand and finger swelling, Raynaud phenomenon, myositis, dermatomyositis or SLE-like rash. Characteristic laboratory findings are, apart from elevated sedimentation rate, anemia and leucopenia, high titer IgM rheumatoid factors and antinuclear antibodies (ANA). The latter show speckled pattern, contain IgG, bind complement components and are directed against ribonuclease-sensitive nuclear antigens. All patients have antibodies against the so-called extractable nuclear antigens (Anti-ENA) and antibodies against ribonucleoproteins (Anti-RNP). Since children with Sharp syndrome rarely show renal or cerebral involvement, the prognosis seems to be fairly good.

Antibodies to ribonucleoprotein (RNP) were detected by an immunofluorescence technique based on the sensitivity of speckled antinuclear antibodies to ribonuclease. These antibodies were found to identify a group of patients with a consistent set of clinical features, especially arthritis, swollen hands, Raynaud's phenomenon, and myositis. The presence of anti-RNP antibodies in sera from patients with polymyositis, systemic lupus erythematosus, and systemic sclerosis was also associated with these clinical features. Other studies of the clinical significance of these antibodies support the concept that they appear to identify a group of patients with a distinct clinical condition.

A case of exophthalmic myositis was identified by a secondary herpes zoster exacerbation. The herpes zoster exophthalmus in this case remained - in contrast to all other cases so far published - free of signs of ophthalmoplegia and retrobulbar neuritis with visual acuity loss.

Immunofluorescent study of the skin of nine patients with mesenchymal, inflammatory scleroderma (mixed connective tissue disease) revealed immunoglobulin and complement deposition at the basement membrane or within blood vessel walls. The skin specimens of ten patients with systemic scleroderma were negative for immunofluorescence. It is proposed that basement membrane or vascular (or both) immunofluorescence is an excellent means of identifying the infrequent patient who has scleroderma and myositis or lupus erythematosus in whom a corticosteroid response may occur.

Clinical and laboratory findings were correlated from 46 patients with IgG localization in epidermal nuclei in a speckled (particulate) pattern on direct immunofluorescence of normal skin. Cutaneous manifestations included lupus erythematosus (LE), swollen hands or sclerodactyly, alopecia, vasculitis, and dyspigmentation. Systemic manifestations included arthritis or arthralgia, Raynaud's phenomenon, serositis, vascular headaches, mild renal disease, myositis, and sicca syndrome. High titer (mean = 1:142, 800) serum antibody to extractable nuclear antigen (ENA) was found in 81%. Eighty-six percent had antibody to an RNase-sensitive antigenic component of ENA (ribonucleoprotein or RNP); 14% had antibody to an RNase-resistant ENA termed Sm. Deposition of IgG in a speckled pattern in epidermal nuclei is an immunopathologic marker for a subset of connective tissue disease characterized by antibody to ENA. Those with Sm specificity had systemic LE (SLE); Those with RNP specificity had Raynaud's phenomenon usually associated with overlapping features of SLE, scleroderma, and/or dermatomyositis.
