1/21. mycosis fungoides with mucinosis follicularis in childhood.mycosis fungoides is a cutaneous T-cell lymphoma (CTCL) usually observed in mid to late adulthood. It occurs only rarely during childhood. Follicular mucinosis is a chronic dermatosis involving the sebaceous glands and outer root sheaths. It is normally differentiated into a juvenile benign form and an adult form possibly associated with mycosis fungoides. We report a 12-year-old boy who presented with an 8-month history of erythematous mucinous plaques on the scalp. Three months later, he developed erythematous patches and plaques on his whole body, accompanied by cervical lymphadenopathy. A biopsy showed follicular mucinosis and epidermotropism of the lymphocytic infiltrate. immunophenotyping and a PCR clonality test were consistent with CTCL. The patient received PUVA treatment and local steroids, resulting in partial remission. mycosis fungoides should be considered in the differential diagnosis of chronic, scaling dermatoses in childhood. Moreover, follicular mucinosis in childhood can be associated with mycosis fungoides.- - - - - - - - - - ranking = 1keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
2/21. Folliculotropic T-cell lymphocytosis (mucin-poor follicular mucinosis).A 48-year-old man presented with multiple asymptomatic patches of hair loss over his trunk and limbs associated with focal keratotic follicular plugs. Multiple skin biopsies showed a panfollicular lymphocytic infiltrate associated with follicular hyperkeratinization, minimal follicular spongiosis, focal basaloid follicular hyperplasia but no overt follicular mucinosis. The lymphocytes were small and there was no atypia. Immunoperoxidase stains showed that the follicular lymphocytes were T cells and predominantly CD4 positive with HLADr (LN3) expressed on their surface. There were insufficient clinical or histopathological features to make a diagnosis of folliculotropic T-cell lymphoma. This case currently may be classified best as folliculotropic T-cell lymphocytosis and may represent a mucin-poor counterpart of follicular mucinosis. Such cases may pursue an indolent course or may evolve to folliculotropic T-cell lymphoma, mycosis fungoides or anaplastic lymphoma. The term folliculotropic T-cell lymphocytosis may be useful for similar cases lacking clinical or histological criteria for lymphoma and lacking follicular mucinosis.- - - - - - - - - - ranking = 0.31072248427617keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
3/21. Rapidly progressing mycosis fungoides presenting as follicular mucinosis.Follicular mucinosis can occur as a primary idiopathic disorder or can arise in association with benign or malignant disease, most notably mycosis fungoides. We describe a patient with an aggressive folliculotropic variant of mycosis fungoides that initially presented as follicular mucinosis with alopecia. One month after the diagnosis of follicular mucinosis, a diagnosis of mycosis fungoides was made, and 3 months later inguinal lymph node involvement with mycosis fungoides developed. A skin biopsy specimen demonstrated prominent follicular mucinosis with folliculotropism of atypical cells and intrafollicular Pautrier's microabscesses. As demonstrated in this case, follicular mucinosis can be a presenting sign of rapidly progressive mycosis fungoides. In our review of follicular mucinosis and its association with mycosis fungoides, we found that the folliculotropic variant of mycosis fungoides appears more commonly to have an aggressive course than classic mycosis fungoides.- - - - - - - - - - ranking = 3.728669811314keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
4/21. alopecia mucinosa and lymphoma. Report of two cases and review of literature.A total of 90 cases of alopecia mucinosa (follicular mucinosis) have been reported in the world literature since Pinkus described the entity in 1957. alopecia mucinosa appears morphologically in any variety of three basic clinical types: grouped folliculopapules, plaque forms of folliculopapules, and as boggy nodular masses. Characteristic histochemical changes of follicular mucinosis have been demonstrated in alopecia mucinosa as well as in selected cases of mycosis fungoides and lymphoma. The majority of case reports of alopecia mucinosa have been in children and young adults (58%), and the course of the dermatosis was usually uneventful. Beyond age 40, the disease appears to behave differently in that it follows a prolonged chronic course, and of 28 cases in this category four (15%) developed into either mycosis fungoides or lymphoblastoma.- - - - - - - - - - ranking = 0.62144496855233keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
5/21. A case of follicular mycosis fungoides with follicular mucinosis: a rare association.Follicular mycosis fungoides (FMF) is a rare cutaneous T cell lymphoma characterized by an atypical lymphoid infiltrate spreading within and around hair follicles without epidermotropism or follicular mucin deposits. Its occasional presentation with minimal epidermal involvement and/or follicular mucinosis suggests the need for uniform histologic criteria. We describe a new case of FMF associated with follicular mucinosis and discuss its morphologic spectrum of presentation.- - - - - - - - - - ranking = 1.5536124213808keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
6/21. Purely follicular mycosis fungoides without mucinosis: report of two cases with review of the literature.Follicular lesions can either associate with typical patch-/plaque-type mycosis fungoides or, more rarely, be the only clinical manifestation of the disease. We describe 2 adult patients who presented with alopecia and disseminated follicular erythematous papules, and comedones and cysts, respectively. In both patients, histology showed a folliculotropic infiltrate of atypical lymphocytes that spared the epidermis, in the absence of follicular mucinosis. Molecular genetic analysis confirmed the oligo/monoclonal nature of the T-cell infiltrate. Reported cases of purely follicular mycosis fungoides without mucinosis are reviewed.- - - - - - - - - - ranking = 1.864334905657keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
7/21. mycosis fungoides with follicular mucinosis displaying aggressive tumor-stage transformation : successful treatment using radiation therapy plus oral bexarotene combination therapy.Follicular mucinosis is a tissue reaction pattern characterized by mucin deposition with follicular sebaceous units and is found as an idiopathic, primary, benign process (alopecia mucinosa), or as a secondary process due to inflammatory and neoplastic disorders (mycosis fungoides). When associated with follicular mucinosis, mycosis fungoides commonly pursues an aggressive course, often undergoing large-cell transformation, which is associated with resistance to therapy and poor prognosis. We present a case of mycosis fungoides with follicular mucinosis that was treated with incomplete courses of interferon, isotretinoin, and polychemotherapy with subsequent rapid progression to tumor-stage mycosis fungoides with large cell transformation and nodal and bone marrow involvement. In this setting, the patient was treated with local radiation therapy, total-skin electron beam therapy, and therapy and maintenance with the oral retinoid-X-receptor retinoid bexarotene, and achieved a durable complete remission.- - - - - - - - - - ranking = 1.4952599580698keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
8/21. alopecia mucinosa is mycosis fungoides.confusion abounds regarding the terms "follicular mucinosis" and "alopecia mucinosa," not only concerning definition and essential character, but of relationships between themselves on one hand and between themselves and mycosis fungoides on the other. We address here those issues in methodical fashion, first in historical perspective by review, scrupulously and critically, of what has been said in the many articles devoted to the subject; we next tell how the terms "alopecia mucinosa" and "follicular mucinosis" came to be and how they are employed currently; we then set forth our own observations pertinent to clinical, histopathologic, and biologic aspects of the condition called, conventionally, "alopecia mucinosa," those observations based on our own findings in sections of tissue cut from 54 biopsy specimens taken from 45 patients, all of them having been signed out previously as "follicular mucinosis;" we proceed to forge clinico-pathologic correlation of lesions in 14 of those 45 patients, utilizing assessments, by examination grossly and microscopically, of attributes in the very same lesion. Last, we propose a concept, and a terminology that derives from it, that synthesizes all that is known now about "alopecia mucinosa" and "follicular mucinosis," in particular the relationship of "alopecia mucinosa" to mycosis fungoides, including "follicular," "syringotropic," and erythrodermic manifestations of it. In short, we affirm that so-called alopecia mucinosa is but one of many morphologic manifestations of mycosis fungoides.- - - - - - - - - - ranking = 2.1750573899332keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
9/21. Follicular mucinosis occurring after bone marrow transplantation in a patient with acute lymphoblastic leukemia.Follicular mucinosis (FM) is characterized histologically by mucinous degeneration of the outer root sheath of the hair follicle and sebaceous gland, accompanied by inflammatory infiltrate. It can occur as a primary idiopathic disorder or in association with benign or malignant diseases, most notably mycosis fungoides. In addition, it also can be found incidentally on histology. We describe an unusual case of follicular mucinosis in a 19-year-old man with acute lymphoblastic leukemia (ALL). One month after bone marrow transplantation, he developed cutaneous graft-versus-host disease (GVHD) involving the palms and soles, which was followed 12 days later by the appearance of multiple erythematous follicular papules and plaques on his face, auricles, and postauricular area. biopsy of follicular plaque revealed changes of follicular mucinosis without evidence of graft-versus-host disease or leukemia cutis. The follicular rash was associated with prominent peripheral eosinophilia. The rash and eosinophilia resolved after 2 and 4 weeks, respectively. In conclusion, we report a case of FM occurring as a transient reaction during the course of cutaneous GVHD following bone marrow transplantation for ALL. awareness of this condition may avoid undue concern that the rash might represent a manifestation of GVHD, cutaneous relapse of the hematological malignancy, or a drug allergy.- - - - - - - - - - ranking = 0.31072248427617keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
10/21. Milia in regressing plaques of mycosis fungoides: provoked by topical nitrogen mustard or not?OBJECTIVE: To report three cases of mycosis fungoides with milia formation in the regressing lesions. patients AND SETTING: dermatology clinic of a university hospital (referral center). Three patients with mycosis fungoides with body surface involvement of 10% in one case (stage IIb) and exceeding 30% in two cases (stages IIb and III). All patients were treated with photochemotherapy and topical nitrogen mustard ointment in a concentration of 0.01%. After approximately 3 months multiple milia erupted on regressing plaques. RESULTS: The presence of milia was evident and was confirmed by histopathology. Regression of mycosis fungoides was noted in these plaques both clinically and in comparison with the pretreatment histologic appearance. Two of the patients showed a histological picture of follicular mucinosis. CONCLUSIONS: We do not know the significance of milia in mycosis fungoides (MF). However, we suggest that follicular rupture or a degenerative process might result in milia formation.- - - - - - - - - - ranking = 2.4857798742093keywords = mycosis fungoides, fungoides, mycosis (Clic here for more details about this article) |
