Physical examination revealed disperse telangiectases and several erythematous-pink papules in the malar regions; one of the telangiectases was larger (6 × 5 mm) and it was decided to biopsy it (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Histopathology revealed a dense lymphocytic infiltrate located in the papillary and reticular dermis with a mixed nodular-diffuse growth pattern and cells with the appearance of centrocytes, together with other, slightly larger cells with the appearance of centroblasts (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). Immune staining was positive for CD10, CD20, CD79a, Bcl-2, and Bcl-6, but negative for CD3 and cyclin D1 (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>).</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0010" class="elsevierStylePara elsevierViewall">Furthermore, monoclonal rearrangement of the gene <span class="elsevierStyleItalic">IgH</span> was detected using PCR (polymerase chain reaction) and rearrangement of the gene <span class="elsevierStyleItalic">Bcl-2</span> was detected using FISH (fluorescence in situ hybridization). Flow cytometry was normal. An initial staging was performed using computed tomography of the chest and abdomen, and blood tests were carried out, including lactate dehydrogenase, but no evidence of systemic disease was found. The findings were thus compatible with primary cutaneous follicle center B-cell lymphoma (PCFCL), which was confirmed following absence of systemic disease after 6 months. A bone-marrow biopsy was not performed due to the painless course of this disease and to the results of the additional tests.</p><p id="par0015" class="elsevierStylePara elsevierViewall">Treatment consisted of intralesional rituximab (anti-CD20 monoclonal antibody) on 6 occasions, with a good response (<a class="elsevierStyleCrossRef" href="#fig0015">Figs. 3</a>A and 3B). The patient subsequently developed a new erythematous papule on the side of the nose (<a class="elsevierStyleCrossRef" href="#fig0015">Figs. 3</a>C and 3D), which, together with the tendency of the patient’s skin toward redness and the presence of disperse telangiectases, produced a a rosaceiform appearance. Topical treatments such as metronidazole and ivermectin were therefore used. Given the lack of response, a new biopsy was taken, which revealed histopathologic findings compatible with PCFCL. The lesions were again treated with intralesional rituximab, a malar lesion and a lesion on the internal occular surface were surgically excised, and complete remission was observed. A watch-and-wait approach was subsequently adopted despite the appearance of new lesions. The patient is currently in joint follow-up with the dermatology and hematology departments, with persistent multiple facial lesions and no extracutaneous involvement.</p><elsevierMultimedia ident="fig0015"></elsevierMultimedia><p id="par0020" class="elsevierStylePara elsevierViewall">Primary cutaneous B-cell lymphoma (PCBL) is a B-cell lymphoma that affects the skin with no signs of extracutaneous disease on diagnosis or in the following 6 months.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> According to records, the follicle center subtype (PCFCL) is the most common form of PCBL, together with primary cutaneous marginal zone B-cell lymphoma.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> Both lymphomas present a painless chronic course, which leads to an approximate 5-year survival rate of ≥95%.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1–4</span></a></p><p id="par0025" class="elsevierStylePara elsevierViewall">Clinically, PCFCL presents firm, asymptomatic papules, plaques, or tumors, in isolation or in erythematous groups, predominantly on the head, neck, and torso.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,5–7</span></a> According to the bibliography described, B-cell lymphoproliferative disorder may mimic a rosacea, although these are extremely rare cases.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,5–7</span></a> In 2012, Barzilai et al<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> recorded 4 cases and in 2004, Seward et al<a class="elsevierStyleCrossRef" href="#bib0035"><span class="elsevierStyleSup">7</span></a> contributed 1 further case, all of which were PCFCL with rosacea or rhinophyma-like clinical lesions.
