Early-onset chronic obstructive pulmonary disease (COPD) is designated as onset under age 50. We report a case of early-onset COPD with recurrent pneumothorax. A 29-year-old woman visited our hospital with productive cough and dyspnea on exertion. CT scan of the chest demonstrated severe panlobular emphysema. A pulmonary function test showed a reduction in FEV1.0 (41% of the predicted value). A diagnosis of severe COPD was made. Her symptoms and pulmonary function improved after the treatment of inhaled corticosteroid, long-acting beta2-agonist, and anti-cholinergic drugs. She had pneumothorax at least 8 times in the right lung. The level of alpha1-antitrypsin was normal. On the basis of the characteristics of the appearance of the chest X-ray and CT scan, the possibility of bronchiolitis obliterans, lymphoangioleiomyomatosis or Langerhans cell histiocytosis was thought to be low. We considered that several factors, such as high susceptibility, pulmonary infection during her childhood, bronchial asthma, malnutrition, smoking history from an early age, and long-term passive exposure to cigarette smoke may have contributed to the development of early-onset COPD in the present case.

Male fertility can be affected by a variety of organs diseases, including the skin. Several genodermatoses affect the skin and several other organs including the male reproductive system, commonly in the form of cryptorchidism and hypogonadism. The most relevant syndromes are associated with dyschromias, such as deSanctis-Cacchione, poikiloderma congenital, LEOPARD, and H syndrome; others with ichthyosis, such as Rud, and trichothiodystrophy; or a group of unrelated genodermatoses, such as ablepharon macrostomia, Coffin-Siris, Gorlin-Goltz, and Werner. Acquired skin diseases may also affect male fertility usually in the form of orchitis or epididymal obstruction or androgen antagonists. These include infections (leprosy and HIV), autoimmune (erythema nodosum leprosum), granulomatous (sarcoidosis, Langerhans cell histiocytosis), nutritional deficiency (zinc), and malignancy. Several therapeutics of skin diseases are notorious for their effects on male fertility, most notably are the cytotoxic drugs (methotrexate), irradiation, and antiandrogens (spironolactone, finasteride). Although the prevalence of these skin diseases is low, the associated male infertility represents a challenge due to the difficulty of its management. Clinical management of the skin diseases should include consideration of their effects not only on the diseases but also on the male reproductive system.

Certain rashes and cutaneous lesions in a newborn can be clues to more concerning diseases and conditions if recognized and evaluated promptly. Langerhans cell histiocytosis, cutaneous forms of cancer (such as leukemia cutis, neuroblastoma, and rhabdomyosarcoma), developmental abnormalities such as neural tube or spinal dysraphism, and aplasia cutis congenita, nutritional deficiency, and immunodeficiency all have a range of cutaneous findings that will be reviewed herein to guide diagnosis and management.
