A bone marrow biopsy was also performed, which showed non-caseous granulomas. There were no clinical or imagiological indications of other organ involvement.

Endobronchial ultrasound biopsy showed non-necrotizing granulomatous infiltration. There were no signs of extrathoracic involvement.

However, the absence of granulomatous disease in other immunodeficiencies (as hypogammaglobulinemia related to X) suggests that GD-CVID is not caused by recurrent/persistent infections.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">6</span></a> A recent hypothesis is that high levels of tumor necrosis factor (TNF) might be related to the development of granulomas in these patients.<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">6,12</span></a></p><p id="par0040" class="elsevierStylePara elsevierViewall">Non-caseous granulomatous lesions that affect CVID patients are histologically indistinguishable from those of sarcoidosis. The patient's age and sex, diminished cellular immunity, the systemic involvement, and high levels of angiotensin-converting enzyme are common features for the two pathologies, so a previous story of recurrent/persistent bacterial infections should raise suspicion of CVID.<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">6,7</span></a> However, in a case–control study comparing GD-CVID patients and patients with pulmonary sarcoidosis, certain differences were detected, such as a random versus perilymphatic micronodular distribution on lung CT scan in GD-CVID patients, besides the higher frequency of consolidations with air bronchogram, bronchiectasis, or halo signs. Biological data showed that BAL CD4/CD8 ratio was significantly lower in GD-CVID. There is a general agreement that the presence of lung involvement is associated with a bad prognosis in CVID, including when a GD-CVID occurs. However Bouvry et al. in their case–control study did not find GD to be a critical determinant of prognosis but found a worse outcome to be linked to the classical complications of CVID such as lymphoma, infection or obstructive lung disease secondary to bronchiectasis.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a></p><p id="par0045" class="elsevierStylePara elsevierViewall">The clinical presentations of the two reported clinical cases, asymptomatic mediastinal and hilar adenopathies and erythema nodosum, are among the most frequent presentations of sarcoidosis. In addition CVID was already known in both patients; however GD-CVID can, although rarely, be the presentation of the disease. The random distribution of the lung micronodules in the first patient and the slight BAL CD4/CD8 increase are in line with previous reports. However, the therapeutic strategy toward this granulomatous disease has diverged. Although corticotherapy is not universally accepted as a mandatory treatment,<a class="elsevierStyleCrossRefs" href="#bib0060"><span class="elsevierStyleSup">12,15</span></a> it was prescribed for the first patient because of the systemic involvement, namely, the cytopenia secondary to the bone marrow involvement.
