shaped hypergranulosis, sawtooth rete ridges, and the presence of colloid bodies at the dermoepidermal junction (Figure 2). The most noticeable aspect from the histological point of view was the intensity of the lymphoid infiltrate, which occupied the whole papillary dermis and reached the upper reticular dermis, obliterating the dermoepidermal junction and also affecting the periadnexal dermis, forming a dense lymphoid accumulation around the sweat glands (Figure 3). These lymphocytes presented no nuclear atypia nor was there a tendency to epidermotropism (Figure 4). Molecular study was performed using the polymerase chain reaction and this detected monoclonal reordering of the TRG gene.
