30 cases of patients with nodule on the thyroid who visited Pediatric Clinic in PUN Hospital from Jan. 1985 till Dec. 1990 were studied and evaluated. All records of the patients were reviewed in regard to the physical examination, thyroid function test, radionuclide scanning, ultrasonogram and pathological findings of the tissues gained by fine needle aspiration or operation. The following results were obtained. 1) Patients with thyroid nodule occupied 7% of all of the goiters who visited the author's clinic during the same period. 2) Male to female ratio was 1:5 predominant in female children. But the ratio was 1:1 in cases of carcinonia. In age distribution, the older, the higher get the incidence. 3) The periods intervening between symptom onset and visiting our clinic were less than 3 months in most of cases. But in one third of the cases, they were neglected for over 1 year. 4) As cardinal symptoms and sings, neck masses were noticed in all of the cases. Easy fatigability, palpitation, sweating and dyspnea were complained of occasionally. 5) In radionuclide scanings, 27 cases had photon defects. All of the carcinoma cases had photon defects. 6) Malignancies were found in 13% of cases. All of malignancies were papillary carcinoma. 7) By palpation, 26 cascs were classified as single nodule, and 4 cases were classified as multiple nodules. But 4 cases among those classified as single nodule revealed multiple photon defect on radionuclide scanning. Because there is significantly high malignancy rate in thyroid nodules as our study showed, all of cases of thyroid nodules in children should be throughly investigated and treated at early stages.

Panniculitis*

Myxopapillary ependymoma generally arise in the conus medullaris and filum terminale of adult spinal cord. These tumors are readily recognized due to unique histopathologic features, however, their cytologic features are not well described. When only a tiny sample is obtained, cytologic examination using crush preparation may be a useful diagnostic tool to help appropriate intraoperative diagnosis. We present the crush cytologic features of myxopapillary ependymoma arising in thoracic and lumbar spinal cord of a 13-year-old boy. The patient had complained of paraparesis and back pain for 1 month. The MRI image revealed a relatively well demarcated intramedullary mass in T11-L1 levels. Crush preparation for cytology were performed by biopsy material. Crush cytologic findings revealed high cellularity and small sized branching papillary clusters on fibrillary or mucinous background. The tumor cells had uniform round or elongated nuclei. The cytoplasmic process of tumor cells were attached to the vascular wall. Between the tumor cells and vascular walls, the perivascular collar of globoid acellular stroma with metachromatic reaction on toluidin blue stain was noted. The crush preparation of myxopapillary ependymoma is considered as a simple and highly accurate diagnostic tool for differentiation from other intramedullary neoplasms of central nervous system.

Cytotoxic T lymphocytes (CTL) playing an important role in e cell-mediated immune response kill the target cells by the special contact-dependent mechanism. It has been known that CTL and NK cells utilize two different pathways in removing specific target cells: apoptotic cell death and osmotic lysis by the pore forming protein. Interaction of CTL with target cells results in the ligand-induced, receptor-mediated, nonsecretory lytic process and lethal hit is delivered by the transducing molecule, Fas (CD95, APO-1), one of the TNFR/NGFR superfamily. In addition, ligation of TNF receptor and CD40 also induced the apoptosis of B cell and epithelial cells. However, recognition of target cells, the triggering mechanism, cytotoxic mediators, internal metabolic pathway and signal transduction behind apoptosis remain undefined and have been elucidated only in part. ...continue...

Follow-Up Studies*

A clinical study was made on 117 cases of benign prostatic hyperplasia admitted to the Department of Urology, Chungnam University Hospital during the period from January 1974 to August 1982. The results were summarized as follows: 1. Common symptoms were dysuria (82.1%) and urinary retention (41.0%). 2. Gross or microscopic hematuria was noticed in 48 cases (41.0%). 3. The degree of prostatic enlargement by rectal palpation was not related to the severity of symptoms. 4. Pulmonary disease (19.5%) and cardiac disease (12.8%) were frequently associated with B.P.H. 5. Treatment consisted of suprapubic of retropubic prostatectomy in 94 cases, TUR in 7 cases and cystostomy in 10 cases. 6. Postoperative complications were urinary incontinence (34%), wound problem (9.7%), delayed bleeding (8.7%), and urinary tract infection (4.8%). 7. Mean weight of removed prostatic tissue was 31.3gm.

The incidence of giant condyloma acuminata of the penis is extremely rare. Although they are considered clinically malignant, the real possibility of malignant changes from them are controversial even among the investigators but cannot be entirely overlooked. Therefore, attention must be focused on this fact, in our conclusion. Two cases of malignancy of the penis which have apparently been transformed from giant condyloma acuminata of the penis are herein presented with review of related literatures. Case I: Sixty nine year old male patient complained of a fungating mass on the sulcus coronaris of the penis with ulceration and bleeding from the mass. Biopsy confirmed giant condyloma acuminata and subsequently circumcision and electrocoagulation were performed. Pathological specimen taken after 4 months because of the recurrence of the mass on the same region showed squamous cell carcinoma of the penis and amputation of penis was performed. Case II: Sixty eight old male patient complained of a growing mass and pain on glans penis. This patient also underwent circumcision and electrocoagulation according to the biopsy finding of giant condyloma acuminata. But 1 year later with recurrence of the mass on the same region, the pathological finding revealed squamous cell carcinoma of penis.
