A Case of Pediatric Follicular Lymphoma in the Parotid Gland / 대한이비인후과학회지

Pediatric follicular lymphoma (PFL) is rare, and it has distinctive characteristics compared to adult-type follicular lymphoma. PFL mainly occurs in males and is likely to be localized to cervical lymph nodes and tonsils. Extranodal type PFL also occurs in the testis, epididymis, skin, gastrointestinal tract, and parotid gland, etc. The prognosis of PFL is better than adulttype follicular lymphoma. Surgical excision is a good option, and the majority of PFL cases show complete remission after surgery. We have encountered a case of PFL of the parotid gland in a 12-year-old boy. Here, we report this case with a review of the literature.

A Case of Superficial Basal Cell Carcinoma Not Correctly Diagnosed with Punch Biopsy but Diagnosed with Dermoscopy / 대한피부과학회지

Basal cell carcinoma is a common cancer and has been reported to account for approximately 80% of non-melanoma skin cancers. Superficial basal cell carcinoma occurs mainly in the trunk or limbs and is characterized by clinical features of scaly erythema with or without epidermal atrophy. These clinical features require differentiation from those of other benign and malignant skin diseases. Recently, specific dermoscopic findings of basal cell carcinoma have been helpful for diagnosis. Common dermoscopic findings of superficial basal cell carcinoma include superficial telangiectasia and maple leaf-like areas. Herein, we report a case of superficial basal cell carcinoma that was not diagnosed by punch biopsy but by dermoscopy.

The Treatments for Low-Risk Prostate Cancer

Recently, the prevalence of prostate cancer has been increased with the screening of prostate-specific antigen and the increase in the elderly population. In particular, the diagnosis of the low-risk prostate cancer has increased greatly, and social interest for overtreatment has been heightened in Korea. Therefore, this review aimed to provide evidence-based treatment guidelines in low-risk prostate cancer based on Korean population. The literature provides evidence on treatment options, such as watchful waiting, active surveillance, radical prostatectomy, and radiation therapy according to the life expectancy of patients with low-risk prostate cancer. Furthermore, this review provides information on the efficacy of pelvic lymph node dissection and adjuvant radiation therapy during/after radical prostatectomy in low-risk prostate cancer.

Influence of Type of Nocturia and Lower Urinary Tract Symptoms on Therapeutic Outcome in Women Treated With Desmopressin

PURPOSE: To investigate the type of nocturia and concomitant voiding dysfunction (VD) and the effect of desmopressin treatment on nocturia in women. MATERIALS AND METHODS: We reviewed 84 women who experienced more than 2 nocturia episodes as recorded on a pretreatment frequency volume chart and who were treated with desmopressin. All patients underwent history taking, physical examination, urinalysis, International Prostate Symptom Score assessment, completion of a urinary sensation scale, and completion of a 3 day frequency volume chart. Nocturia was divided into nocturnal polyuria (NP), reduced nocturnal bladder capacity (RNBC), and mixed type. After treatment with desmopressin, a reduction in nocturia of over 50% compared with baseline was regarded as effective. RESULTS: Among 84 women, the most common concomitant VD was overactive bladder (OAB, 60.7%). NP was observed in 70.2% (59/84) of the women, RNBC in 7.1% (6/84), and mixed type in 22.6% (19/84). After medication with desmopressin, 73 women (86.9%) showed a significantly reduced number of nocturia episodes (1.4+/-1.5) compared with baseline (3.7+/-1.3, p<0.05). Eleven women (13.1%) did not show improvement. Of the 73 women who showed improvement, 41 women showed a reduction of more than 50% over baseline, and these women had a lower baseline urgency grade. CONCLUSIONS: In the majority of women, nocturia coexisted with other VD such as OAB. Treatment with desmopressin effectively reduced the nocturia. However, other lower urinary tract symptoms (LUTS) such as urgency may reduce the effect of desmopressin. Therefore, consideration of concomitant LUTS seems to be necessary to increase the treatment effect of desmopressin on nocturia in women.
