We reviewed surgical specimens from 11 patients with diffuse neurofibroma to define the specific clinicopathologic characteristics. Ten cases were cutaneous neurofibromas and one case was an uncommon gastrointestinal neurofibroma involving the rectum. The most frequent sites of involvement were the head and neck, especially the eyelids and the periorbital areas. They usually presented as a plaque-like elevation of the skin. They primarily occured in children and young adults and positive family histories of von Recklinghausen's neurofibromatosis were obtained in 45.4%. Pathologically, the involved skin & rectum were diffusely thickened by an infiltrative growing mass, showing proliferation of short fusiform cells in the uniform matrix of fine fibrillary collagen. The characteristic prominence of Wagner-Meissner bodies (45.4%) suggests they could be associated with pathogenesis of diffuse neurofibroma. On the basis of these findings, we could confirm diffuse neurofibroma to be a distinct form of neurofibroma.

Polymorphous light eruption(PMLE) is an idiopathic, scquired syndrome characterized by a delayed abnormal response to light and a varied morphology of recurrent erythema, papules, vesicles or plaques on light-exposed areas of skin. We report herein s 42-year-old male patient who was clinically and histologically compatible with PMLE. To confirm the diagnosis, the phototest was performed by 50,J/crn of UVA, 5MED-UVB and visible light irradiation to the extensor surface of the forearm. Numerous erythematous papules developed at the (JVA-irradiated site. The histopathologic findings of the phototest induced lesion were compatible with PMLE. Therefore, our patient was confirmed as having PMLE with action spectrum in the IJVA range.

Acardiac twinning affects 1 in 100 monozygotic twin pregnancies and 1 in 35,000 pregnancies overall. This condition is characterized by the absence or rudimentary development of fetal heart, and associated with various anomaly. The presence of an acardiac twin requires the normal (or "pump") twin to provide circulation for itself, as well as the acardiac sibling. The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. The principal perinatal problems associated with acardiac twinning are pump-twin congestive heart failure, maternal hydramnios, and preterm delivery. We recently experienced a case of acardius anceps associated with a normal male infant, so present with a brief review of the literature.

Magnetic Resonance image(MRI) is used as the diagnostic modality for evaluation of suspected intramedullary tumors and differential diagnosis of these tumors at the spinal cord. We experienced intramedullary astrocytoma of cerviced cord with large syrinx and multiple peritumoral cysts consisted of subacute and chronic hemorrhage at the margin and within the syrinx and cysts on MRI.

Failure of a glaucoma filtering operation mainly results from scarring at the filtering wound, and postoperative proliferation and migration of fibroblasts play an important role histologically in the formation of scar tissue. As an inhibitory agent for fibroblast proliferation, gamma-interferon has been introduced, and the application of gamma-interferon following filtering surgery is now being made on a trial basis. We studied the effect of gamma-interferon histologically on the fibroblast proliferation and collagen synthesis occurring at the filtering site by comparing the effect of gamma-interferon on the experimental group with that of 5-fluorouracil on the control group, using 10 rabbits (20 eyes) after posterior lip sclerectomy. Both groups showed similar flat and diffused bleb grossly and also showed a similar inhibitory effect on fibroblast proliferation and collagen fiber synthesis histologically. Our findings seem to justify the clinical use of gamma-interferon. Further studies on adequate dosage, method of administration, and local and systemic complications would be desired.
