Involvement of the tongue by lymphomatoid papulosis

Oral manifestation of lymphomatoid papulosis: systematic review

Introduction: Lymphomatoid Papulosis (LyP) is a lymphoproliferative disorder with typical histopathological criteria and a spontaneous regression. Only few cases of oral involvement have been reported. We wondered about their clinical characteristics and their association with lymphoma. Method: This systematic review is conducted according to the PRISMA statement. The Oxford Centre for Evidence Based Medicine table (OCEBM) and the scoring from the National Agency for Accreditation and Assessment in Health (ANAES) was assigned to each study. Results: We have included 16 references. LyP can occur at any age with a female predilection. Oral lesions were unique ulcer and tongue was mostly affected. Histological types A, and C were dominant and LyP resolved spontaneously. 1 case was associated with a lymphoma. Discussion: Cutaneous LyP more affects men and are mostly classified as type A while those orals are type A or C. Oral LyP is probably a progressive lesion whose evolution is not illustrated by the histological aspect which often reflects only the initial acute period. Conclusion: Our literature review has shown that the epidemiological aspects between oral and cutaneous LyP are not the same. LyP may be associated with an increased risk of developing systemic lymphoproliferative disorders.

An unusual case of cluster of differentiation 30-positive T-cell lymphoproliferative disorder manifesting as mandibular gingival ulceration: A case report

BACKGROUND

Primary cutaneous cluster of differentiation 30-positive (CD30+) T-cell lymphoproliferative disorders are the second most common type of skin T-cell lymphoma. The lesions exhibit an indolent course, with a morphology resembling high-grade T-cell lymphoma.

CASE DESCRIPTION

A 67-year-old healthy man sought treatment for a large nonhealing ulcer on the buccal gingiva of the mandibular right premolars. He reported a history of recurrent cutaneous lesions, for which he was seen 1 year earlier at a hospital. Results of incisional biopsy showed a dense lymphoid cell infiltrate composed of atypical CD30+ T-cells intermixed with eosinophils. The diagnosis was updated to CD30+ T-cell lymphoproliferative disorder, which was similar to the cutaneous lesion diagnosis. The lesion area healed completely, and there were no signs of recurrence at 18-month follow-up.

PRACTICAL IMPLICATIONS

Oral CD30+ T-cell lymphoproliferative disorder has a favorable outcome, but it is commonly misdiagnosed. Biopsy is crucial and should be combined with clinical examination to avoid chemotherapeutic treatments intended for high-grade lymphoma.

Acral lymphomatoid papulosis: Report of five cases, differential diagnosis, and review

Acral lymphomatoid papulosis (a-LyP) is a rare clinical variant of LyP whose diagnosis may be challenging. A case series of a-LyP was studied clinically, histopathologically, immunohistochemically, and from molecular point of view. Including ours, 25 cases of a-LyP have so far been reported. Clinically, a-LyP may present as acral involvement exclusively, in combination with mucosal lesions, (in itself a rare presentation), or in association with conventional LyP. The age of presentation was slightly higher than that of conventional LyP (55 vs 45 years) and a male predominance has been observed, as usually reported. Histopathologically, no morphological differences exclusively from conventional LyP were observed. LyP types A and E were the main variants. We describe for the first time one case of type D a-LyP. Acral LyP is a rare entity and correct diagnosis can only be reached with clinical and histopathological correlation, to avoid aggressive treatment of this indolent lymphoproliferative disorder.

Lymphomatoid papulosis localized to the oral mucosa: case report and literature review

Introduction: Lymphomatoid papulosis is a primary CD 30+ cutaneous lymphoproliferation. Observation: We report the case of a 39-year-old patient who presented with ulcers on the back of the tongue, gums, buccal mucosa, and soft palate, which evolved as spontaneously regressive flare-ups. The diagnosis of inflammatory bowel disease was initially proposed. Several years later, the patient presented an ulcer on the left middle finger. Histological examination confirmed the diagnosis of lymphomatoid papulosis. Discussion: This chronic dermatosis manifests a single rash or multiple papulonodular rashes, evolving as spontaneously regressive flare-ups. Mucosal involvement is rare, and no prognostic factor for this location has been highlighted to this date. Pathological examination is essential. Conclusion: The mucosal involvement of lymphomatoid papulosis is one of the diagnoses to be considered for recurrent mouth ulcers.

Pediatric oral Epstein-Barr virus associated self-remitting CD30+ lymphoproliferative disorder: A distinct entity

Epstein-Barr virus (EBV) has a well-known association with lymphoproliferative disorders of B and T cell origin. EBV-related B cell lymphoproliferative disorders include Hodgkin and Burkitt lymphomas, lymphomatoid granulomatosis, EBV positive diffuse large cell B cell lymphoma of the elderly, as well as B cell lymphomas associated with solid organ transplantation and methotrexate use. EBV-related T cell disorders are primarily represented by NK/T- cell lymphoma. In a subset of patients, EBV has been implicated in CD30 positive B cell lymphoproliferative disorders of the oral mucosa falling under the rubric of the mucocutaneous ulcer of the oral cavity. We previously reported on an index series of endogenous CD30 positive T cell lymphoproliferative disorder of the oral cavity resembling borderline type C lymphomatoid papulosis. The clinical manifestation of type C oral lymphomatoid papulosis is that of a recurrent self-remitting ulcer of the oral mucosa, which histologically resembles anaplastic large cell lymphoma. Such cases can be misdiagnosed as aggressive lymphoma leading to unnecessary treatment with aggressive chemotherapeutic regimens. Whereas none of the patients in our index series exhibited EBV positivity, here we discuss a very unique example of a 14-year-old girl diagnosed with EBV positive CD30 positive lymphoproliferative disorder strongly resembling the cases of intra-oral type C lymphomatoid papulosis. The patient was initially diagnosed by a senior hematopathology consultant as having EBV positive aggressive NK/T-cell lymphoma. The significance of raising physician awareness regarding pediatric oral EBV associated CD30 positive lymphoproliferative disease of the oral cavity lies in preventing inadvertent exposure to toxic chemotherapeutic agents intended for treatment of aggressive look-alikes, namely anaplastic large cell lymphoma. Additionally, we include a literature review of similar reports of pediatric intra-oral EBV positive CD30 positive T cell lymphoproliferative disease.

The spectrum of primary mucosal CD30-positive T-cell lymphoproliferative disorders of the head and neck

OBJECTIVE

To retrospectively investigate the clinicopathologic spectrum of primary mucosal CD30-positive T-cell lymphoproliferative disorders (PTCLDs) of the head and neck.

STUDY DESIGN

Archives of PTCLDs primarily arising in head and neck mucosa were reviewed. Immunostaining of CD20, CD3, CD4, CD8, CD30, CD56, anaplastic lymphoma kinase (ALK), epithelial membrane antigen (EMA), cytotoxic molecules (TIA-1, granzyme B, or perforin), and Ki67; in situ hybridization for Epstein-Barr virus; and T-cell receptor gene rearrangement analysis were performed.

RESULTS

Fourteen cases of primary mucosal anaplastic large cell lymphoma (M-ALCL) were identified, and no lymphomatoid papulosis (LyP) cases were found. All cases demonstrated atypical mononuclear neoplastic cells with diverse histology and cytomorphology. The typical immunophenotype of neoplastic cells was CD3-positive, CD4-positive, CD8-negative, CD30-positive, ALK-negative, and cytotoxic molecules-positive. Infiltration of inflammatory cells was common. All cases presented an indolent course, regardless of therapy.

CONCLUSIONS

PTCLDs of the head and neck provisionally included M-ALCL alone.

Mucosal CD30-positive T-cell lymphoproliferations of the head and neck show a clinicopathologic spectrum similar to cutaneous CD30-positive T-cell lymphoproliferative disorders

CD30-positive T-cell lymphoproliferative disorders are classified as cutaneous (primary cutaneous anaplastic large cell lymphoma and lymphomatoid papulosis) or systemic. As extent of disease dictates prognosis and treatment, patients with skin involvement need clinical staging to determine whether systemic lymphoma also is present. Similar processes may involve mucosal sites of the head and neck, constituting a spectrum that includes both neoplasms and reactive conditions (eg, traumatic ulcerative granuloma with stromal eosinophilia). However, no standard classification exists for mucosal CD30-positive T-cell lymphoproliferations. To improve our understanding of these processes, we identified 15 such patients and examined clinical presentation, treatment and outcome, morphology, phenotype using immunohistochemistry, and genetics using gene rearrangement studies and fluorescence in situ hybridization. The 15 patients (11 M, 4 F; mean age, 57 years) had disease involving the oral cavity/lip/tongue (9), orbit/conjunctiva (3) or nasal cavity/sinuses (3). Of 14 patients with staging data, 7 had mucosal disease only; 2 had mucocutaneous disease; and 5 had systemic anaplastic large cell lymphoma. Patients with mucosal or mucocutaneous disease only had a favorable prognosis and none developed systemic spread (follow-up, 4-93 months). Three of five patients with systemic disease died of lymphoma after 1-48 months. Morphologic and phenotypic features were similar regardless of extent of disease. One anaplastic lymphoma kinase-positive case was associated with systemic disease. Two cases had rearrangements of the DUSP22-IRF4 locus on chromosome 6p25.3, seen most frequently in primary cutaneous anaplastic large cell lymphoma. Our findings suggest mucosal CD30-positive T-cell lymphoproliferations share features with cutaneous CD30-positive T-cell lymphoproliferative disorders, and require clinical staging for stratification into primary and secondary types. Primary cases have clinicopathologic features closer to primary cutaneous disease than to systemic anaplastic large cell lymphoma, including indolent clinical behavior. Understanding the spectrum of mucosal CD30-positive T-cell lymphoproliferations is important to avoid possible overtreatment resulting from a diagnosis of overt T-cell lymphoma.

Chronic lingual papulosis: new, independent entity or "mature" form of transient lingual papillitis?

OBJECTIVE

Several acute, usually pediatric variants of edematous, symptomatic fungiform lingual papillitis have been reported since the 1990s, most notably transient lingual papillitis (TLP); but no chronic forms have been mentioned. Is there a chronic counterpart, akin to the older palatal examples of inflammatory papillary hyperplasia? The objective of this study was to clinicopathologically characterize a previously unreported entity with clustered, chronic fibrous papules (nonsyndromic) of the tongue.

METHODS

Cases were collected from clinics in 2 dental schools.

RESULTS

Five women and 4 men were identified with multiple, moderately firm, slightly pedunculated, normally colored masses clustered at the tip of the tongue (n = 4), covering the dorsal surface (n = 4) or on the lateral border (n = 1); 2 showed several erythematous or edematous papules (similar to TLP) admixed with fibrous papules. Patient ages ranged from 31 to 62 years (average 49) and all lesions had been present for many years. All lesions were asymptomatic except for the lateral border lesion, which presented with a burning sensation and mild tenderness (disappeared with antifungal medication). Five cases were associated with mouth breathing or a tongue-thrust habit; 4 were associated with geographic tongue or fissured tongue. Four papules were biopsied. All were composed of dense, avascular fibrous tissue with no or very few inflammatory cells; one showed focal mild neovascularity and edema. The lesion appeared to represent altered filiform papillae, more so than fungiform papillae.

CONCLUSIONS

Chronic lingual papulosis (CLP) is an innocuous entity represented by focal or diffuse enlargement of numerous lingual papillae, primarily the filiform papillae. It appears to usually have an adult onset and most likely represents papillary reaction to very low-grade, chronic irritation or desiccation. Some cases with childhood onset, however, seem to be variations of normal anatomy. No treatment or biopsy is required, but a number of systemic disorders and syndromes must be ruled out before applying the CLP diagnosis.

Cutaneous hematologic disorders in children

BACKGROUND

To determine and list the clinical and pathological features of cutaneous hematologic diseases in childhood.

PROCEDURE

We retrospectively analyzed the data for 51 patients up to 15 years of age, who presented with primary cutaneous hematologic disorders according to the WHO-EORTC classification, at Necker-Enfants Malades Hospital, Paris, France, over a 17-year period. The cases were classified into the following diagnostic categories: CD30+ T-cell lymphoproliferative disorders (24) all consisting of lymphomatoid papulosis (LyP, 24), lymphoblastic lymphoma (LL, 7), acute leukemias (AL, 7), mycosis fungoides (MF, 5), Epstein-Barr virus-related lymphoproliferative disorders (EBV-related LPD, 5), T/NK-cell lymphoma, nasal type (1), γ/δ T-cell lymphoma (1), and panniculitis-like T-cell lymphoma (1).

RESULTS

We encountered a majority of LyP. No secondary lymphoma was found in LyP patients with a median follow-up of 8 years. 29% and 80% of LyP and MF patients, respectively, presented with pityriasis lichenoides chronica (PLC) before onset of disease. Owing to a frequently misleading clinicopathological presentation, MF patients were first underdiagnosed. Clinicopathological features of LL and AL were highly stereotypical, leading to the diagnosis being suspected and confirmed more promptly. In the latter patients and in EBV-related LPD patients, skin lesions usually led to the discovery of systemic disease.

CONCLUSION

Distribution of cutaneous hematologic diseases seems to be different in adults and in children aged <15-year old. PLC was strongly correlated with MF and LyP. Physicians must be made aware of the stereotypical clinical presentations of LL and AL to allow prompt diagnosis and treatment.

T-cell receptor gene rearrangement and CD30 immunoreactivity in traumatic ulcerative granuloma with stromal eosinophilia of the oral cavity

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is an ulcerative lesion of the oral mucosa with unknown pathogenesis. A few recent case reports have demonstrated molecular evidence of T-cell clonality in TUGSE and CD30 immunoreactivity in the large atypical mononuclear cells, raising the possibility that a TUGSE subset may represent the oral counterpart of primary cutaneous CD30+ T-cell lymphoproliferative disorders. We examined the immunoreactivity for CD30 and T-cell receptor (TCR) gamma gene rearrangement in 37 TUGSE cases. Clonal TCR gene rearrangements were demonstrated in 7 (24%) of 29 cases with amplifiable DNA, and the morphologic features and CD30 immunoreactivity of these cases did not differ from those with polyclonal TCR gene rearrangements. Clinical follow-up was available for 5 of 7 TUGSE cases with clonal TCR gene rearrangement for an average period of 1.75 years after the initial biopsy or excision, and there was no evidence of local recurrence or development of systemic T-cell lymphoproliferative disorder. Without morphologic and/or clinical evidence of lymphoma, T-cell clonality and/or CD30 positivity in these lesions is not indicative of malignancy and should be interpreted with caution.

CD30-Positive T-Cell Lymphoproliferative Disorder of the Oral Mucosa—An Indolent Lesion: Report of 4 Cases

Four cases of CD30-positive T-cell lymphoproliferative disorder (CD30+ LPD) of the oral mucosa are described. This article aims to draw attention to this entity and to emphasize its usual benign clinical behavior despite its resemblance to T-cell lymphoma. All the patients were adults. Three of the lesions were on the dorsal surface of the tongue and 1 affected the buccal mucosa. All biopsies showed a dense lymphoid infiltrate composed of CD30+ atypical T cells with a polymorphous infiltrate in the background, which included eosinophils. In 1 case, monoclonal T-cell expansion was detected by molecular techniques. Three cases tested for Epstein—Barr virus were all negative. It is concluded that primary CD30+ T-cell LPD of the oral mucosa can be regarded as the oral counterpart of cutaneous CD30+ LPD such as lymphomatoid papulosis or anaplastic large cell lymphoma. Recognition of the condition is important to avoid overtreatment.

Eosinophilic ulcer of the oral mucosa: another histological simulator of CD30+ lymphoproliferative disorders

Eosinophilic ulcer of the oral mucosa (EUOM), also known as traumatic ulcerative granuloma with stromal eosinophilia or Riga-Fede disease, is an uncommon benign self-limited lesion poorly described in the dermatological literature. It probably includes a spectrum of related disorders presenting as an ulcer with elevated indurated borders affecting the tongue, oral mucosa or lip. Histopathological findings are characteristic and consist of eosinophil-rich mixed infiltrates accompanied by a population of large mononuclear cells whose origins have been a matter of debate. Immunohistochemical studies of these cells have suggested a myofibroblastic or histiocytic origin. We present a 93-year-old woman with two episodes of self-healing ulcers on the upper lip and on the lingual mucosa, respectively. Histopathological findings on both biopsies were consistent with EUOM and showed the presence of large atypical CD30+ lymphocytes. Some recent reports have also shown positivity for the CD30 antigen, raising the possibility that a subset of EUOM could be included within the spectrum of CD30+ lymphoproliferative disorders. This finding most likely suggests that EUOM can represent another histological simulator of CD30+ lymphoproliferative disorders.

Oral Involvement in Lymphomatoid Papulosis

Oral involvement in cutaneous CD30+ T-cell lymphoid proliferations is rare and has received little attention in the dermatologic literature. The authors report 2 patients with self-healing, recurrent papulonodular eruptions with the classic clinical, histopathological and immunophenotypic features of lymphomatoid papulosis, which developed two ulcerated papules and an ulcerative nodule on the dorsum of the tongue, respectively. The lesions appeared coincident with a new cutaneous relapse of the disease. Histopathological and immunophenotypic features were similar to those of the cutaneous lesions. All lesions regressed spontaneously after several weeks. Since then, and after follow-up periods of 3 and 7 years, respectively, no evidence of extracutaneous involvement has been detected. Oral involvement in lymphomatoid papulosis is an uncommon event, probably without prognostic significance. Previously reported cases are reviewed. The differential diagnosis of atypical T-cell lymphoid infiltrates observed in the oral mucosa is discussed.

Mucosal involvement in a patient with lymphomatoid papulosis

We report a 38-year-old woman with lymphomatoid papulosis (LyP) who had nodular and papulovesicular lesions develop on the genital area and oral commissure. Mucosal involvement in LyP is a rare event, and its clinical relevance is still unknown. Aggressive therapies are not recommended in patients with LyP with either cutaneous or mucosal involvement.

Critical review of lymphomatoid papulosis of the oral cavity with case report

A 60-year-old woman was referred to the Department of Dental Medicine at Long Island Jewish Medical Center for evaluation of multiple lesions of the tongue. She reported a long history of recurrent papular cutaneous eruptions that waxed and waned. A biopsy specimen of one of the cutaneous lesions was diagnosed as lymphomatoid papulosis. Sporadic, recurrent oral ulcers that resolved spontaneously were noted 10 to 14 days before the initial visit. These ulcers had recurred for the past 17 years. The most recent oral lesion was an erythematous, irregular, solitary ulcerated area on the middle third dorsum of tongue. The area quickly enlarged, ultimately developing extensive surface necrosis. Shortly after, a similar lesion on the posterior dorsum of the tongue developed. Biopsy specimens of the former lesion showed numerous, large, atypical, pleomorphic, and hyperchromatic cells with abundant mitoses. The large, atypical cells were immunohistochemically proven to be T lymphocytes. A diagnosis of lymphomatoid papulosis was made. Two weeks later, the tongue lesions had spontaneously and totally resolved. The clinical, histomorphologic, and immunohistochemical features, as well as gene rearrangement studies of this rare entity, are presented.
