Trichogenic tumors are very rare and described as cutaneous neoplasms probably derived from hair germ which develops into hair follicles. We report a case of trichoblastic fibroma on the left parietal scalp of a 45-year-old man. The lesion was a solitary, firm, non-tender, 2×2cm subcutaneous nodule. The histopathological study showed a well circumscribed dermal tumor composed of abundant basophilic palisading basaloid lobules with some keratinous cysts, hair follicle differentiation and fibroblastic stroma.

To determine the comparative accuracy of two Doppler tests, the findings of 38 patients who had undergone a complete evaluation by supraorbital Doppler test, frontal Doppler test and angiography were studied. When stenosis of 60 percent or more in diameter was considered as a true positive finding, the Doppler tests of 76 internal carotid arteries of the 38 patients showed the following results. Supraorbital Doppler test: eight false positive, three false negative, and 65 correct findings, with an overall accuracy of 85%. The authors, therefore, concluded that the suprorbital Doppler test was more sensitive and accurate than the frontal Doppler test in screening the patients with possible carotid artery occulusive diseases.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.

BACKGROUND: The purpose of our investigation was to evalute response to therapy and prognosis according to clinical and pathologic stage. METHODS: Fourteen children who had LCH were diagnosed between Jan., 1987 and Dec., 1996. Of the 14 patients, 3 patients with only skin involvement were excluded from this study. The medical records of 11 patients were reviewed for organ involvement at diagnosis, treatment, disease course, and late sequelae. Results: 1) As for the clinical stages, 4 patients were in stage I, 4 in stage II, one in stage III, and 2 in stage IV. As for the pathologic stages, four had monostotic disease, 2 polyostotic disease and 5 multisystemic disease. 2) All six patients with monostotic and polyostotic disease had a complete response to the therapy and remain alive free of disease. Three of the five with multisystemic disease had a complete response to the therapy, while two had a progression of disease. 3) Sequelae were observed in 3 patients including 2 with diabetes insipidus and 1 with hepatic and pulmonary dysfunctions. 4) The median follow-up time from diagnosis for all patients was 3.5 years. The Kaplan-Meier estimate of survival rate is 91%, with estimated EFS of 81.8% at 5 years. CONCLUSION: The clinical outcome of LCH patients with single system involvement including monostotic and polyostotic diseases were favorable and all remains alive free of disease. Multisystemic disease was associated with several unfavorable prognostic features including diagnosis at age <2 year, dysfunction of involved organs and advanced clinical stage.
