Spontaneous pneumothorax (SPTx) associated with primary lung cancer is quite rare, but has been reported as the initial presentation or a complication of disease progression. Moreover, chemotherapy-related SPTx in primary lung cancer occurs at a very low frequency, accounting for less than 0.05% of all cases. Here, we report the first case of erlotinib-related SPTx in a patient with advanced lung adenocarcinoma in Korea. After 3 cycles of cisplatin-based chemotherapy as first-line therapy, erlotinib was administered as second-line treatment. Asymptomatic SPTx accompanied by a significant decrease in tumor size was observed in the left lung 7 weeks later. The patient received continuous administration of erlotinib, without additional treatment. This case showed that SPTx can occur in patients with primary lung cancer receiving erlotinib, and asymptomatic chemotherapy-related SPTx in primary lung cancer may not require therapeutic intervention.

Background: Patient reported outcome measures assess clinical progress from the patient's perspective. This study explored the relationship between shoulder outcome measures (The Disability of the Arm, Shoulder and Hand [DASH], American Shoulder and Elbow Surgeons Standard Shoulder Assessment score [ASES], and Constant score) by comparing the best possible scores obtained in an asymptomatic population compared to overall perception of health, as measured by the SF-36 outcome measure. Methods: Volunteers (age range, 20-69 years) with asymptomatic shoulders and no history of shoulder pain, injury, surgery, imaging, or pathology (bilaterally) were included. The DASH and ASES measures were completed by 111 volunteers (72 female, 39 male), of which 92 completed the Constant score (56 female, 36 male). The SF-36 was completed by all volunteers (level of evidence: IV case series). Results: The mean (${\bar{x}}$) score for ASES measure on the right shoulder was higher for the left-hand dominant side (${\bar{x}}=100.00$ vs. 95.02, p-value<0.001); no other significant differences. Better SF-36 scores were associated with better DASH scores. Our prediction models suggest that perception of overall health affects the DASH scores. Sex affected all three shoulder measures scores. Conclusions: Comparing scores of shoulder outcome measures to the highest possible score is not the most informative way to interpret patient progress. Variables such as health status, sex, and hand dominance need to be considered. Furthermore, it is possible to use these variables to predict scores of outcome measures, which facilitates the healthcare provider to deliver individualized care to their patients.

Hepatitis B surface antigen (HBsAg) seroclearance is a rare event in chronic hepatitis B virus (HBV) infection which acquires the disease early in life. A case study have examined with asymptomatic chronic hepatitis B carrier who exhibits HBsAg seroclearance in anti-HBe positive. We comprehensively studied the biochemical, virological and clinical aspects of a patient with HBsAg seroclearance. Liver biochemistry, serological markers, serum HBV DNA levels, and development of clinical complications were monitored. Mutation of hepatitis B virus is suspected serum HBsAg detected by the HBsAg assay systems of VITROS (OrthoClinical Diagnostics, USA), AxSYM (Abbott Laboratories, USA), Elecsys (Roche Diagnostics, Germany) and ADVIA Centaur (Bayer Diagnostics, USA). These four immunoassays showed negative results. Also, the patient had undetectable serum HBV DNA. Therefore, no mutation within the "a" determinant of HBsAg, which might escape detection from HBsAg immunoassay were found. Natural seroclearance was confirmed.

We encountered a patient with heavy Hymenolepis nana infection. The patient was a 44-year-old Korean man who had suffered from chronic hepatitis (type B) for 15 years. A large number of H. nana adult worms were found during colonoscopy that was performed as a part of routine health screening. The parasites were scattered throughout the colon, as well as in the terminal ileum, although the patient was immunocompetent. Based on this study, colonoscopy may be helpful for diagnosis of asymptomatic H. nana infections.

Thyroid cancer is known as its relatively high cure rate after surgical treatment and spinal metastasis of thyroid cancer is extremely rare as the prevalence is only 2-13%. Spinal metastasis is usually asymptomatic and discovered incidentally in most cases. A 66-year-old man was diagnosed as thyroid papillary cancer with spinal metastasis. We treated the patient by surgery, adjuvant radiotheraphy and radioactive iodine therapy. C6 corpectomy was followed for the residual spinal metastasis by the department of neurosurgery. The patient had no functional complication by the surgical process. At 24 months after surgery, there was no sign of recurrence and the patient led social life without any discomfort. We present this case with a review of the related literatures.

Preauricular sinus is a congenital malformation that is very commonly encountered among the general population and it has especially high prevalence among Asians when compared to other ethnic groups. It can often go unnoticed or easily overlooked by the patient or even by doctors because most of them are asymptomatic and is most of the time only a tiny pit that can be trivial in terms of aesthetics. We report a very rare and unique case that has no precedence what so ever; hence no reported case in the literature: an ectopic preauricular sinus in a facial cleft and microsomia patient.

We report a case of large radicular cyst progression related to endodontic origin to emphasize proper intervention and follow-up for endodontic pathosis. A 25 yr old man presented with an endodontically treated molar with radiolucency. He denied any intervention because of a lack of discomfort. Five years later, the patient returned. The previous periapical lesion had drastically enlarged and involved two adjacent teeth. Cystic lesion removal and apicoectomy were performed on the tooth. Histopathological analysis revealed that the lesion was an inflammatory radicular cyst. The patient did not report any discomfort except for moderate swelling 3 days after the surgical procedure. Although the patient had been asymptomatic, close follow-ups are critical to determine if any periapical lesions persist after root canal treatment.

Essential thrombocytosis (ET) is a myeloproliferative disorder characterized by an anomalous increase in platelet production. Many patients with ET are asymptomatic. Few studies have reported ET-associated thromboembolism in large vessels such as the aorta. We report a patient with ET who presented with peripheral embolism from an abdominal aortic thrombus and developed acute limb ischemia. The patient underwent aortic replacement successfully. The patient's platelet count was controlled with hydroxyurea, and no recurrence was noted over 2 years of follow-up.

Although carbohydrate antigen (CA) 19-9 is a useful tumor marker for pancreatic cancer, it can also become elevated from a variety of benign and malignant conditions. Herein we describe an unusual presentation of elevated CA 19-9 in an asymptomatic patient who had previously undergone adjuvant chemotherapy and radiation therapy for resected early stage pancreatic cancer. The rise in CA 19-9 might be due to delayed radiation-induced inflammation related to previous intra-abdominal radiation therapy with or without radiation recall induced by gemcitabine. After treatment with corticosteroids the CA 19-9 level decreased to normal, and the patient has not developed any evidence of recurrent cancer to date.
