[Acanthosis nigricans over the face revealing primitive bronchial adenocarcinoma: about a case].

We here report a case of bronchial cancer revealed by acanthosis nigrigans affecting the face. This rare mode of revelation may precede diagnosis of underlying neoplasia by several months . This study highlights the importance of suspecting primary lung cancer in patients with acanthosis nigrigans.

Prevalence and risk factors for latent tuberculosis infection among healthcare workers in Morocco.

Increased prevalence of latent tuberculosis infection (LTBI) has been observed among high-risk populations such as healthcare workers (HCWs). The results may depend on the method of LTBI assessment, interferon-gamma release assay (IGRA) and/or tuberculin skin test (TST). Here, we investigated the prevalence and risk factors for LTBI assessed by both IGRAs and TST in HCWs living in Morocco, a country with intermediate tuberculosis (TB) endemicity and high BCG vaccination coverage.

[A rare infectious etiology of COPD exacerbation].

Chronic obstructive pulmonary disease (COPD) is a common respiratory disorder. Its exacerbation is infectious in more than half of the cases: with viral priority, while parasitic causes remain exceptional. In this work, we report a case of a COPD exacerbation caused by a visceral leishmaniasis (VL) complicated by a macrophage activation syndrome in an adult living in a Moroccan non-endemic region for this of leismaniasis form.

Unusual mode of presentation of intrathoracic bronchogenic cyst: A double location.

A 63 year old woman presenting chronic back pain and neuralgia had abnormal shadow on chest radiograph. She has a history of pulmonary tuberculosis treated in 1977. The chest-CT scan showed a soft tissue mass in the lower lobe of the right lung and a cystic mass in the paravertebral region.

[Sarcoïdose in patient with chronic hepatitis C treated with pegylated interferon].

Induced sarcoïdosis during therapy with interferon for chronic viral hepatitis C involves mainly by isolated cutaneous lesions or with lung lesions. Systemic forms are very rare. We report an observation.

[Hemoptysis revealing an endobronchial metastasis of testicular choriocarcinoma].

The choriocarcinoma are neoplasms developed from testicular germ cells in men or fetal trophoblasts in women. The most common sites for metastatis are in the lung, but the endobronchial location is unusual. We report the case of a young patient of 27 years, hospitalized for hemoptysis of moderate volume, occurring in the context of deterioration in his general condition.

Intrathoracic extrapulmonary hydatid cysts.

Hydatid disease caused by echinococcus granulosus is still a serious problem in both underdeveloped and developing countries. Clinical signs of the disease are not specific. Most patients have a few symptoms when a hydatid cyst is discovered.

Malignant melanoma of the lung: a case report.

Primary melanoma of the lung is an extremely rare pathological entity and sparsely reported in the literature. A 68-year-old man was admitted with 3 months history of cough, sputum production, dyspnea, hemoptysis and chest pain. The chest radiography demonstrated bilateral mass lesion and thoracal computerized (CT) showed a bilateral tissu mass with left parietal invasion.

Diffuse large B-cell lymphoma presenting as large anterior chest wall mass involving pleura and lung: A possible result of post-traumatic chronic inflammation.

A 67 year-old-man was hospitalized due to chronic pain and a large mass on the anterior chest wall. His medical history showed chest trauma in 1970, the reconstitution of the scenario revealed there was blunt trauma with swelling and rib fracture on the same side. Physical examination revealed an isolated large anterior chest wall mass.

[Adrenal tuberculosis: case report].

Isolated adrenal tuberculosis is rare, and represents between 1-2% of the etiologies of adrenal masses called incidentalomas. A 32-year-old woman, without notable medical history, was hospitalized for pain in the left hypochondrium, lasting for two months in a context of apyrexia and weight loss amounted to 5 kg. Clinical examination was normal, but abdominopelvic CT objectified bilateral adrenal hypertrophy predominantly left with bilateral linear calcifications.

Desmoplastic small round cell tumor of the pleura.

In July 2006 a 19-year-old woman presented with a history of few months of back ache. Routine chest radiograph and computed tomography (CT) examination revealed a thickening of the parietal pleura with a collapsed right lung. The abdominal pelvic CT scan was normal.

A well-differentiated fetal adenocarcinoma of the lung with early local recurrence after limited resection.

A 42-year-old man was found to have an abnormal shadow during a systematic physical examination. Computed tomography of the chest revealed a mass in the lateral segment of the left lower lobe with parietal contact without pleural effusion or mediastinal lymphadenopathy. Bronchoscopy showed inflammation at the pyramid basal bronchus without visualization of hydatid materials or bud tumor.

[A rare cause of posterior mediastinal tumors: extramedullary hematopoiesis].

We report a case of a patient with intrathoracic extramedullary hematopoiesis presenting as a posterior mediastinal tumor, without associated myelofibrosis. Pathophysiology and the options for diagnosis and treatment in this condition are discussed.
