RESUMO
BACKGROUND: Previous studies have shown that at least a of intraoral eosinophilic ulcer is best classified as a CD30 + T-cell lymphoproliferative disorder (LPD), with histopathology reminiscent of lymphomatoid papulosis (LyP) of the skin. Microscopically, a mixed population of inflammatory cells, often including eosinophils and varying numbers of atypical lymphoid cells, frequently expressing CD30, is typical for LyP, whose clinicopathological spectrum includes type A, B, C, D, E, and LyP with DUSP22/IRF4 rearrangement. To date, about 27 intraoral LyP cases have been reported. Of them, 7 cases were diagnosed as LyP type C, which is frequently confused with anaplastic large cell lymphoma (ALCL) on histopathology. METHODS: A 60-year-old male was referred for a one-month history of a tongue ulcer. RESULTS: Microscopy showed numerous subepithelial atypical large lymphoid cells, which expressed CD4 (with partial loss of CD3, CD5, and CD7), CD8 (few cells), CD30 (about 50%, in non-diffuse pattern with size variability), TIA-1, and Ki-67 (85%), without staining for CD56, ALK, LMP1, and EBER1/2, concerning for a diagnosis of ALCL. However, after three weeks, the lesion completely healed. CONCLUSION: We present here a rare case of intraoral CD30+ T-cell LPD that we believe is the oral counterpart of cutaneous LyP type C.

BACKGROUND: An increased risk of Secondary Malignancies (SMs) in Mycosis Fungoides (MF) has been suggested previously. However, the relationship between this risk and the features of MF is not well-known. OBJECTIVE: To investigate the rate and types of SMs in a large cohort of MF patients focusing on the associated features of these patients. METHODS: The demographic features, subtype, and stage of MF, as well as the temporal relationship between the diagnosis of MF and the development of SMs were determined. Major clinical features of MF in this group were compared with MF patients without association of SMs. RESULTS: Among 730 MF patients with a mean follow-up period of 67.9 ± 52.4 months, 56 SMs were identified in a total of 52 (7.1%) patients. While 28.8% of patients were previously diagnosed with other malignancies, then subsequently had a diagnosis of MF, it was vice versa in 53.8% of patients. Most of the SM-associated MF patients had early-stage (80.7%) and classical type of MF (86.5%) without a significant difference from MF patients without association of SMs; 85.5% and 72.5%, respectively. The most commonly identified SMs were hematologic malignancies (64.3%) including lymphomatoid papulosis (n = 22), Hodgkin's lymphoma (n = 4), non-Hodgkin's lymphoma (n = 5), polycythemia vera (n = 2). Other most commonly associated malignancies were breast cancer (n = 4), prostate cancer (n = 3), renal cell carcinoma (n = 2), melanoma (n = 2), and Kaposi's sarcoma (n = 2). STUDY LIMITATIONS: A single tertiary dermatology center study with a retrospective design. CONCLUSION: Apart from the well-known lymphomatoid papulosis association, systemic hematological malignancies were also quite common in the large cohort of MF patients.

RESUMO
A 59-year-old man with Hodgkin's lymphoma was referred by a hematologist for consultation for cutaneous issues. Physical examination revealed generalized scaling and erythematous scaly patches located in the groin, abdomen, and arms. The biopsy was compatible with mycosis fungoides (MF). At his next medical visit, painful nodules with erythematous halo and scabby surface were noted, and a subsequent biopsy was compatible with lymphomatoid papulosis (LyP). Mycosis fungoides, the most common primary cutaneous T-cell lymphoma, is usually defined in its classic form as a CD4+ non-Hodgkin lymphoma; LyP corresponds to a CD30+ lymphoproliferative disorder; and Hodgkin's lymphoma (HL) constitutes a lymphoid neoplasia characterized by the presence of Reed-Sternberg cells and its variants. Although these entities have been defined independently, evidence suggests the possibility of a common monoclonal origin. To our knowledge, this is the first case of MF, LyP, and HL in a single patient.
RESUMO
Bowenoid papulosis (BPap) is an uncommon skin disorder linked to human papillomavirus (HPV) infection and characterized clinically by the presence of scattered papules or small plaques, multiple and pigmented, that involve the stratified squamous epithelium. Bowen disease (BD) is recognized as the main differential diagnosis of BPap. An 80-year old white woman was referred for the evaluation of multiple, brown verrucous papules measuring 3 to 4 mm in diameter on the right maxillary gingiva. Histopathological analysis revealed disturbed epithelial maturation with papillary stratified squamous epithelium, koilocytic dysplasia, parakeratosis, acanthosis, basal double-layer, loss of cellular polarity, nuclear hyperchromatism and pleomorphism, scattered mitosoid bodies, and a high degree of cytologic atypia. An immunohistochemical investigation for p53 and Ki67 showed staining of the basal and suprabasal layer, while p16 was strongly expressed in the nuclei of epithelial cells and Bcl-2 was positive only in mitosoid bodies and the lymphocytic inflammatory infiltrate. In situ DNA hybridization was negative for HPV. Oral BPap is an uncommon lesion in which the diagnostic process includes clinical, histopathological, and molecular correlations due to the similarity to aggressive behavior lesions such as BD.

RESUMO
La papulosis fibrosa blanca del cuello es una patología benigna, que se presenta frecuentemente en personas mayores y que se caracteriza por pápulas blanquecinas ubicadas habitualmente en las regiones laterales del cuello. El hallazgo histopatológico distintivo es el incremento de las fibras de colágeno en la dermis papilar. Su etiopatogenia es, hasta ahora, desconocida y su tratamiento es difícil. Dado que corresponde a una patología infrecuente, probablemente subdiagnosticada, es que se decide reportar el caso de una mujer chilena de 77 años.
White fibrous papulosis of the neck is a benign pathology, which usually occurs in old people and is characterized by whitish papules that are frequently located in the lateral regions of the neck. The distinctive histopathological finding is the increase of collagen fibers in the papillary dermis. Its pathophysiology is not currently known and its treatment is difficult. Due to being a rare pathology, probably underdiagnosed, it was decided to report the case of a 77-yearold chilean woman.

La papulosis linfomatoide forma parte del espectro de los procesos linfoproliferativos cutáneos primarios de células T CD30+. Es una enfermedad rara de etiopatogenia incierta y compleja. El diagnóstico diferencial puede a veces resultar muy difícil. Se describió el caso de una mujer de 80 años con el diagnóstico, particularmente atípico desde la visión histopatológica, en el cual la correlación anatomoclínica ha sido un importante aspecto que lo hace interesante. El objetivo es comunicar un caso de presentación poco frecuente en la práctica médica (AU).
Lymphomatoid papulosis is part of the primary skin lymph proliferative processes of the T CD30+ cells. It is a rare disease of complex and uncertain etiopathogenesis. The differential diagnosis could be very difficult sometimes. The described case was the one of a female patient, aged 80 years with that diagnosis, particularly atypical from the histopathological point of view, where the anatomoclinical correlation has been an important aspect making it interesting. The objective is to inform a case of infrequent presentation in the medical practice (AU).

Lymphomatoid papulosis (LyP) is defined as a chronic, recurrent, self-healing papulonecrotic or papulonodular skin disease with histologic features suggestive of a (CD30-positive) malignant lymphoma. In up to 20% of patients, LyP are preceded by, associated with, or followed by another type of cutaneous or systemic lymphoma, generally mycosis fungoides (MF), primary cutaneous anaplastic large cell lymphoma (C-ALCL). In this case, we describe a case of MF that preceded and continued to coexist with LyP type C.(AU)
A papulose linfomatóide (LyP) é definida como uma doença cutânea papulonecrótica ou papulonodular crônica, recorrente, com características histológicas sugestivas de linfoma maligno (CD30-positivo). Em até 20% dos pacientes, o LyP é precedido por, associado ou seguido por outro tipo de linfoma cutâneo ou sistêmico, geralmente micose fungóide (MF), linfoma cutâneo primário de células grandes anaplásicas (C-ALCL). Neste caso, descrevemos um caso de MF que precedeu e continuou a coexistir com LyP tipo C. (AU)

Abstract: The classification of cutaneous lymphomas is multidisciplinary and requires the correlation between clinical, histopathological, immunohistochemical, and molecular diagnostic elements. In this article, we present four different cases of CD30-positive T-cell lymphoma with cutaneous manifestations. We compare cases with definitive diagnosis of papulosis lymphomatoid type C, primary cutaneous anaplastic large T-cell lymphoma, systemic anaplastic large T-cell lymphoma with secondary skin involvement, and mycosis fungoides with large cell transformation, highlighting the importance of clinicopathological correlation to classify these cases.
