Tuberous sclerosis complex (TSC) is an autosomal dominant and multi-system genetic disorder in humans. TSC affects around 25,000 to 40,000 individuals in the United States and about 1 to 2 million individuals worldwide, with an estimated prevalence of one in 6,000 newborns. TSC occurs in all races and ethnic groups, and in both genders. TSC is caused by defects or mutations in two genes, TSC1 and TSC2. Loss of TSC1/TSC2 leads to dysregulation of mTOR, resulting in aberrant cell differentiation and development, and abnormal enlargement of cells...

OBJECTIVES: Pulmonary Langerhans cell histiocytosis (PLCH) is a rare interstitial granulomatous disease that usually affects young adults who are smokers. Chest computed tomography (CT) allows a confident diagnosis of PLCH only in typical presentation, when nodules, cavitated nodules and cysts coexist and predominate in the upper and middle lungs. METHODS: This article includes a pictorial essay of typical and atypical presentations of PLCH at initial chest CT. Various appearances of PLCH are illustrated and possible differential diagnosis is discussed...

PEComa is a mesenchymal neoplasm thought to derive from the perivascular epithelioid cell, a hypothetical cell type not yet identified. PEComa is a broad term that was recently expanded to include visceral, retroperitoneal, and somatic soft tissue, in addition to cutaneous tumors, which share morphological and immunohistochemical features in common with angiomyolipoma, lymphangiomyomatosis, and clear cell "sugar" tumor. The latter have distinct, site-related, clinical, morphological, and biological features...

OBJECTIVES: We report our experience of lobar lung transplantations (LLTs) in patients with small thoracic volume. METHODS: Since 1988, 50 LLTs were done for cystic fibrosis (n=35), fibrosis (n=7), bronchiectasis (n=3), emphysema (n=3) and lymphangiomyomatosis (n=2). There were 44 females and 6 males (mean age 31±13 years, mean size 155±5.5 cm and mean predicted total lung capacity (TLC) 4463±598 ml). Mean ratio between donor and recipient-predicted TLC was 1...

BACKGROUND: The number of lung transplantation has tended to increase as a treatment for patients with pulmonary arterial hypertension (PAH) and lymphangiomyomatosis (LAM) in Japan. However, we have little evidence about the comparison of perioperative management in patients with PAH and that in patients with LAM. METHODS: In this retrospective study, ten patients with PAH and seventeen patients with LAM who underwent the lung transplantations between 2006 and 2011 were enrolled...

We present a case of multifocal micronodular pneumocyte hyperplasia (MMPH), lymphangiomyomatosis (LAM) and angiomyolipoma (AML) in a 33-year-old woman with tuberous sclerosis complex referred to us during her first pregnancy. Computed tomography of the chest showed diffuse micronodules and cysts in both lungs. Compared to those before pregnancy, the number of micronodules increased evidently. We hypothesized the micronodules in both lungs were either LAM, MMPH, or a combination of the two. Bilateral renal AML also intensified...

Rapamycin (sirolimus) is a fungal fermentation product that inhibits the proper functioning of a serine/threonine protein kinase in mammalian cells eponymously named mammalian target of rapamycin, or mTOR. Rapamycin is a novel class of anticancer and immunosuppressant drugs targeting the proteins at molecular level. Rapamycin (sirolimus) is routinely incorporated in drug-eluting stents used for cardiac angioplasty. In recent years, rapamycin was found to be efficacious in managing the symptom complex of tuberous sclerosis, i...

Septal, reticular, nodular, reticulonodular, ground-glass, crazy paving, cystic, ground-glass with reticular, cystic with ground-glass, decreased and mosaic attenuation pattern characterise interstitial lung diseases on high-resolution computed tomography (HRCT). Occasionally different entities mimic each other, either because they share identical HRCT findings or because of superimposition of patterns. Idiopathic pulmonary fibrosis (IPF), fibrosis associated with connective tissue disease, asbestosis, end-stage sarcoidosis or chronic hypersensitivity pneumonitis (HP) may present with lower zone, subpleural reticular pattern associated with honeycombing...

Lymphangiomyomatosis (LAM) is a rare lung disease that is characterized by the progressive proliferation of atypical smooth muscle-like cells, which leads to severe respiratory impairment and death. Dyspnea, cough, recurrent pneumothorax, and hemoptysis are the most common clinical symptoms of LAM. We report a 29-year-old female patient with massive hemoptysis during laparoscopic gynecologic surgery under general anesthesia, who was diagnosed with pulmonary LAM.

Perivascular epithelioid cell (PEC) neoplasms are an unusual group of mesenchymal tumors thought to arise from the PEC, which characteristically expresses melanocytic markers with common coexpression of muscle markers. They show a wide morphologic spectrum and have been described in multiple anatomical locations, including the uterus. We report a 59-year-old woman with tuberous sclerosis, initially diagnosed with a uterine malignant mixed müllerian tumor, in whom the hysterectomy specimen also showed 3 other incidental tumors: a subserosal angiomyolipoma consisting of blood vessels of varying caliber, mature adipose tissue, and nests of spindle cells arranged in a perivascular location, a sclerosing PEComa consisting of small nests of clear epithelioid cells present in a background of marked sclerosis centered in the lower uterine segment/endocervix, and diffuse lymphangiomyomatosis involving the endocervix, lower uterine segment, and uterine corpus...
