Lupus-like lesions in X-linked chronic granulomatous disease (X-CGD) are rare. To our knowledge, only 2 cases have previously been published. We report a 2.5-year-old boy with X-CGD whose clinical findings were consistent with cutaneous lupus erythematosus. Conventional histopathology showed epidermal atrophy, parakeratosis, follicular plugging and areas of hydropic degeneration. The most striking feature was a neutrophilic interstitial infiltrate with leukocytoclasia in the upper dermis. The X chromosome of our patient--studied with 2 endonucleases (PstI and TaqI) and 5 probes (P99.6, pERT 87.8, pERT87.15, XJ1.1 and 754)--was recombinant, but we believe that this is an incidental finding, not related to the disease. Neutrophilic infiltrate and leukocytoclasia could be characteristic histopathologic findings of lupus-like lesions in these patients.

In the newly revised World Health Organization (WHO)-European Organization for Research and Treatment of Cancer (EORTC) consensus classification for cutaneous lymphomas, cutaneous gamma/delta T-cell lymphoma (CGD-TCL) has been included as a provisional entity. This type of lymphomas, when involving the subcutaneous fat, can mimic both clinically and histologically other more indolent conditions, such as subcutaneous panniculitic T-cell lymphomas (SPTCL) and lupus erythematosus profundus (LEP), and multiple biopsies may be needed to obtain a correct diagnosis. A good correlation of the clinical data with the histopathology and immunohistochemistry are required for diagnosis. Herein, we describe a patient whose initial histopathologic findings ressembled LEP but presented an aggressive clinical course. A new biopsy was performed during the follow-up, and a final diagnosis of CGD-TCL was made.

Here we describe two term male infants diagnosed with X-linked CGD who present, in addition to frequent infection, with a unique papulopustular skin rash. CGD is caused by a number of genetic defects that impair phagocyte function. This disease results in recurrent infections and granuloma formation. Rarely do patients develop cutaneous symptoms, unless associated with autoimmune disorders such as systemic erythematous lupus (1). Each male infant mentioned here was diagnosed with CGD based on abnormal DHR testing and confirmatory genetic testing. The presenting papulopustular dermatitis was initially characterized as non-classic appearing eczema and subsequently found to be refractory to usual eczema treatment and antibiotics. After obtaining written informed consent from both families, we have documented photographs of the development of a characteristic rash in two newly diagnosed infants with CGD. One infant underwent cutaneous biopsy with histologic evaluation and negative cultures. The dermatitis for both infants was refractory to topical and systemic therapies, and resolved after bone marrow transplantation. Our objective was to characterize cutaneous findings in X-linked CGD and emphasize the importance of considering further immune workup in patients who present with unusual cutaneous findings that do not fit with common infant rashes in conjunction with concerning features for primary immunodeficiency.
