“…6,7,10,13 This may be due to the exclusion of some less bulky nasal cases with limited diagnostic samples from our study. Referral bias is also important since nasal and cutaneous disease may be referred initially to otolaryngology or dermatology centers, 21,22 and the diagnostic material may not be kept after review at the tertiary oncology center. This may also explain the lower incidence of extranasal disease in Japan, which is discordant with previous retrospective series.…”

“…La diseminación a médula ósea en un estudio retrospectivo de 57 sujetos fue positivo en 3 pacientes, siendo dos de ellos linfoma cutáneo primario de célula B tipo centro folicular y el restante tipo cutáneo marginal, y tan solo 3 estudios hablan de la realización de biopsia de médula ósea como procedimiento de rutina (6,8). Así mismo una biopsia positiva cambia tanto el pronóstico, sobrevida y tratamiento a seguir.…”

ResumenLos linfomas cutáneos primarios de células B constituyen cerca del 20-25% de todos los linfomas. El linfoma cutáneo primario de células B tipo centro folicular es el subtipo más frecuente y se manifiesta principalmente en pacientes adultos con una edad media de 58 años (1), la diseminación extra-cutánea es muy rara y se presenta con nódulos, tumores o placas solitarios o en grupo usualmente localizados en cabeza o tronco. Presentamos el caso de una paciente con un linfoma primario cutáneo tipo centro folicular con infiltración a médula ósea.Palabras clave: Linfomas cutáneos de células B, linfoma centro folicular. PRIMARY CUTANEOUS FOLLICLE CENTER LYMPHOMA WITH BONE MARROW INFILTRATION AbstractPrimary B cell cutaneous lymphomas represent approximately 20-25% of all lymphomas. Primary cutaneous follicle center lymphoma is the most common subtype occurring in adults with a mean age of 58 years. The disease typically presents with solitary plaques or nodules and is usually located in the head or trunk. Extra cutaneous dissemination is extremely rare. We present a case of a patient with primary cutaneous follicle center lymphoma with bone marrow infiltration.

“…The estimated annual incidence of this condition is 1:100,000 in the USA [66]. The proportion of the T-cell subtype is higher in Korea (81.6-84.3 %) [67,68] and Japan (80-86.8 %) [69,70] than it is in the USA (71.3 %) and Europe (77.6 %) [71,72]. The most common subtypes in Western countries are MF/SS, CD30?…”

The frequency of PTCL of primary cutaneous T-cell lymphomas (PCTLs) is variable, ranging 9.2-12.3 % in Korea and from 4.3 to 16 % in Japan [67][68][69][70]. PTCL encompasses PTCL, NOS, primary cutaneous cd T-cell lymphoma (cdTCL), primary cutaneous CD8?…”

Peripheral T-cell lymphomas (PTCLs) comprise a heterogeneous group of mature T-and NK-cell neoplasms, the incidence of which is higher in Asian countries than in Western countries. Although its etiology is mainly unknown, several risk factors (such as genetic factors, abnormal immunity, environmental factors, and infectious causes) have been proposed. PTCL are classified based on a combination of several parameters, including morphology, site of presentation, viral status, immunophenotype, and specific genetic alterations. Their classification is ongoing, with the emergence of new entities and refinement of existing entities because of the development of diagnostic markers and new genetic alterations. This review presents epidemiologic data for PTCL in Asia, together with recent progress in the pathology of PTCL compared with the WHO 2008 classification.Epidemiology T-and NK-cell lymphomas are uncommon: overall, they represent fewer than 25 % of all non-Hodgkin's lymphoma (NHL) [1][2][3]. The occurrence rates of various subtypes of T-and NK-cell lymphomas in Asia are significantly different from those observed in Western countries, and even among Asian countries. The incidence and distribution of T-and NK-cell lymphomas in several Asian countries is summarized in Fig. 1 and Table 1 [ [4][5][6][7][8][9][10][11][12][13][14][15].The frequencies of T-and NK-cell lymphomas seem to increase from West to East Asia. The occurrence rate of Tand NK-cell lymphomas are relatively low (\20 % of NHL) mainly in West Asia (Turkey 16.2 %, Iraq 19 %, and Kuwait 18 %) and South Asia (Pakistan 11.3 %, and India 20.2 %), but relatively high mainly in East Asia (China 32.5 %, Korea 22 %, and Japan 24.9 %) and Southeast Asia (Thailand 25 %). The proportion of T-and NK-cell lymphomas in Taiwan is very low (13.3 %) compared with that of other East Asian countries. Regarding the subtypes of T-and NK-cell lymphomas, two West (Turkey and Iraq) and one South (Pakistan) Asian countries share similar distribution patterns, presenting T lymphoblastic lymphoma (T-LBL) as the most common subtype, followed by peripheral T-cell lymphoma (PTCL) or anaplastic largecell lymphoma (ALCL). The frequency of mycosis fungoides/sezary syndrome (MF/SS) is very high in Kuwait. The distribution patterns of T-and NK-cell lymphomas in Thailand, Taiwan, and Korea are similar, whereas adult T-cell leukemia/lymphoma (ATLL) represents a high proportion of T-and NK-cell lymphomas in Japan. When ATLL is excluded, four countries (Thailand, Taiwan, Korea, and Japan) exhibit very similar patterns of subtype distribution of T-and NK-cell lymphomas. Extranodal NK/ T-cell lymphoma (ENKL) is frequent in China (48 %) and Korea (28.7 %), but is less frequent in Japan (10.4 %), as reported by a recent study performed by an international T-cell project [2]. In China, the frequency of T-or NK-cell lymphoma varies according to geographic region
