A Case of Spontaneous Regression of Non-small-cell Lung Cancer / 결핵및호흡기질환

Lung cancer is one of the most prevalent cancers and it has the highest mortality of all forms of cancers. Although surgery, chemotherapy and radiotherapy are routinely used for the treatment of lung cancer treatment, little progress has been made in the treatment of this condition over the past 20 years. The histological subtype of squamous cell carcinoma (SCC) accounts for approximately 30% of all lung cancer patients. Spontaneous regression of non-small-cell lung cancer (NSCL) is an extremely rare phenomenon. Spontaneous regression of cancer (SR) is defined as a complete or partial, temporary or permanent disappearance of all or at least some the relevant parameters of soundly diagnosed malignant disease without any medical treatment or with treatment that is considered inadequate to produce the resulting regression.

A Case of Advanced Gastric Cancer and the First Symptom was a Skin Lesion / 대한소화기내시경학회지

Cutaneous metastasis of internal malignancies is rare and the incidence of metastatic skin lesions as the first symptom of disease is only 0.8% for patients with all types of malignancies. Furthermore, cutaneous metastasis from advanced gastric cancer is exceedingly rare. A 43-year-old man presented with a single, symptomatic, erythematous nodule on the chest wall. A biopsy taken from the nodule showed an adenocarcinoma of the poorly differentiated type. An endoscopic examination and biopsy was done and these showed the same histologic findings. We reported here on this unusual case of advanced gastric cancer and the patient's first symptom was a skin lesion.
