A 60 year old male with a long standing history of smoking was referred to our department for surgery of aspergilloma in right upper lung lobe diagnosed by computed tomography and confirmed by computed tomography guided needle aspiration biopsy. A lobectomy was performed. Histological study of the surgical specimen revealed a pulmonary adenocarcinoma associated with aspergilloma. By presenting this case we suggest that every case of pulmonary aspergillome should be examined for malignancies, especially in smokers.

In Morocco, pulmonary aspergilloma is most commonly diagnosed in a patient with a healed tuberculous cavity. It rarely affects healthy people with an intact immune response, but those with preexisting structural lung disease, atopy, occupational exposure or impaired immunity are susceptible. Aspergillosis can remain asymptomatic or present with hemoptysis, which can be life-threatening . In this report, we describe a fortuitous discovery of unsuspected lung adenocarcinoma in surgical resection performed for aspergilloma of the right upper lobe.
Twelve months later, the patient is going well with stable X- rays.
Four distinctive patterns of Aspergillus related lung diseases are recognized, as follows: saprophytic colonization, pulmonary aspergilloma, hypersensitivity induced aspergillosis and invasive pulmonary aspergillosis .
Pulmonary aspergilloma (PA), or intracavitary fungus ball, is commonly found in cavities such as those seen in cases of sequelar tuberculosis, bronchiectasis, lung cyst and abscess, bullae, pulmonary infarcts, cystic fibrosis, histoplasmosis, sarcoidosis, HIV infection and cavitated squamous cell lung cancer . It is typically caused by Aspergillus fumigatus, although other species may be associated with its formation, usually in the upper lung fields. The diagnosis of PA is usually established radiologically by demonstrating the characteristic appearance of the fungus ball and confirmed by Aspergillosis serology and/or by CT guided needle aspiration biopsy, as in the case here present.
In one study, the prevalence of Aspergillus growth in patients with cavitary or non-cavitary bronchogenic carcinoma was reported as being 14.2% , but only a few cases of combined aspergilloma and lung cancer have been reported in the literature  because development of an aspergilloma in a cavity associated with a malignant tumor is very unusual.
In the most of the cases, the diagnosis had not been considered preoperatively. The meniscus or air crescent sign is most often associated with benign diseases such as aspergilloma, however, one should remember that carcinoma can be combined , especially when patient had an anti fungal agent and the image does not change or continues to increase, when the fungus ball-like shadow is fixed to a thick and irregular wall of the cavity and its position is not altered with the patient's movements  and particularly in case of preexisting factor of lung cancer. Frozen section examination of a Wedge excision of aspergilloma performed by video assisted thoracoscopic surgery or thoracotomy must be followed, and when a cancer is combined, a carcinologic surgery and médiastinal lymph node dissection is done.
We suggest that when aspergilloma is found in healthy persons with no risk factors, lung cancer must be ruled out by frozen section of a pulmonary excision of aspergilloma. If combination is confirmed, a carcinologic surgery with mediastinal lymph node dissection must be performed.
Written informed consent was obtained from the patient for publication of this case report and accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal.
