INTRODUCTION: Perianal pseudolymphoma is a rare lymphoproliferative disorder that can mimic cutaneous lymphoma. The condition can present acutely with concerns of perianal sepsis. The purpose of this case review is to review the current literature on perianal pseudolymphoma and emphasise to the surgical community its presentation, suggested aetiology and management. CASE PRESENTATION: In this case report, we detail the case of a 28-year-old female who presented with perianal pseudolymphoma...

Pseudolymphoma is a drug reaction to anti-epileptics that is well recognized in humans; it has been reported in one cat but not dogs. In this report, lymphoma-like clinical signs are suspected to be secondary to phenobarbital administration in a dog. A 2.5-year-old male, neutered Shepherd mix presented for a 3-day history of progressive ataxia, dazed mentation, pyrexia, and lethargy. While hospitalized, the dog developed generalized lymphadenopathy and sustained pyrexia. The dog was receiving levetiracetam and phenobarbital for epilepsy, and serum concentrations of both were within standard therapeutic ranges...

Here, we present the case of a 50-year-old woman diagnosed with stage I hormone-dependent breast cancer. The patient underwent partial mastectomy followed by adjuvant radiotherapy and hormone treatment with tamoxifen. Three years later, she presented with a solitary liver lesion on MRI, which was highly suspicious of malignancy. However, several fine needle biopsies were performed, and histopathological examination revealed no signs of neoplasia. As a result of these alarming discrepancies, the multidisciplinary board recommended a diag-nostic laparotomy, which yielded a finding consistent with reactive lymphoid hyperplasia, a pseudolymphoma of the liver, on a background of incipient steatohepatitis...

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

Acral angiokeratoma-like pseudolymphoma is a rare type of pseudolymphoma presenting as dark-red papules on the hand or foot. We describe a 59-year-old woman who presented with an unusual unilateral, clustered aggregate of scaly violaceous papules on the toe with an indolent course. Skin biopsy showed a prominent vascular proliferation associated with a dermal infiltrate of monoclonally rearranged T-follicular helper phenotype T-cells, in keeping with CD4+ small/medium T-cell lymphoproliferative disorder (SMPTC-LPD)...

A two-year-old female spayed domestic shorthair cat was presented with apathy, inappetence and generalised lymphadenomegaly. Anamnestic data included a generalised seizure disorder and phenobarbital treatment started one month before presentation. Routine blood analysis revealed only mild abnormalities and FeLV and FIV tests were negative. Both popliteal lymph nodes were aspirated and cytology was consistent with reactive lymph node hyperplasia. PCR for antigen receptor rearrangement testing diagnosed a polyclonal cell population...

BACKGROUND: Mycosis fungoides (MF) is a significant diagnostic challenge; it has various differential diagnosis especially at an early stage. Our aim was to describe mimics of MF clinically and histologically, and to define significant diagnostic criteria of the disease. METHODS: This was a retro-prospective cohort of 370 patients in whom the diagnosis of MF was suspected clinically. RESULTS: MF was histologically confirmed in 15.4% of cases and rejected in 84...

Cutaneous Leishmaniasis (CL) is endemic in 88 countries, showing relevant prevalences. The aim of this study was to perform a systematic review on atypical lesions of CL around the world, addressing clinico-epidemiological, immunological and therapeutic aspects. A search of the literature was conducted via electronic databases Scopus and PubMed for articles published between 2010 and 2015. The search terms browsed were "cutaneous leishmaniasis", "atypical" and "unusual". Based on the eligibility criteria, 34 out of 122 articles were included in the final sample...

Lymphocytic infiltrations located in the extracellular matrix often accompany canine skin cancer. They can be characterised as an inflammatory infiltration and/or a second tumour - lymphoma. The aim of this study was an immunohistochemical analysis of a lymphocytic infiltration which accompanies spontaneous skin cancer. Twenty basal cell carcinoma, 20 non-keratinizing squamous cell carcinoma, 20 keratinizing squamous cell carcinoma and 8 sebaceous gland carcinoma samples which were accompanied by a lymphocytic infiltration and/or secondary lymphatic follicles were verified histopathologically...

Immune-mediated drug reactions are a potentially life-threatening complication of antiseizure medications. Drug hypersensitivity syndrome (DHS) is the best recognised of these, presenting with fever, eosinophilia, rash and internal organ involvement. Isolated lymphadenopathy is a less recognized immune-mediated reaction to antiseizure drugs such as lamotrigine. We describe the case of a 24-year-old woman who developed lamotrigine-related bilateral cervical lymphadenopathy (pseudolymphoma) fifteen months following therapy initiation...

Diagnosis of tattoo complications is a multi-facetted field since many clinical entities and disease mechanisms are represented. Infections, allergies, and pigment foreign body reactions with granuloma are the major groups. The clinician needs a structured approach to diagnosis and an armamentarium of standard tests. Diagnosis primarily builds on patient history, objective clinical examination, and punch biopsy, supplemented with microbiology testing, ultrasound scanning, and clinical photography. Evaluation of allergic tattoo reactions and allergy to pigments by patch testing is not applicable and has a falsely negative outcome except for the diagnosis of allergy to metals and preservatives...

Cutaneous lymphoid hyperplasia (CLH) is a cutaneous pseudolymphoma with a worldwide distribution, equally affecting all races and ethnic groups. Due to its vast array of characteristics, it is most often missed in the differential diagnosis of firm to soft lumps on the head and neck. A systematic approach to the workup and diagnosis along with treatment of such lesions is discussed in this article. A 20-year-old Asian Indian female presented to our Oral and Maxillofacial unit with a lump on the left side of her forehead for 1 month...

Erythema annulare centrifugum (EAC) is a clinical reaction pattern that includes lupus erythematosus, spongiotic dermatitis (particularly pityriasis rosea), pseudolymphoma and cutaneous B-cell lymphoma. However, it can be the result of cutaneous metastasis by an internal carcinoma. We present the case of a 38-year-old woman with bilateral inflammatory breast cancer following multimodal therapy. After chemotherapy, the patient developed EAC on her back, clinically suspect of subacute cutaneous lupus erythematosus...

In the last twenty years, the prevalence of individuals with tattoos in the general population has increased in Europe (1) as well as in Australia (2) and the United States of America (3). A series of complications such as acute inflammatory reactions, allergic contact dermatitis (4,5), photoinduced, lichenoid, and granulomatous reactions (6, 7), pseudolymphoma (8), pseudoepitheliomatous hyperplasia (9), skin infections (6), and skin cancers (10) may occur on tattoos. Infectious complications on tattoos include bacterial infections (pyoderma, leprosy, syphilis, cutaneous tuberculosis, mycobacteriosis) (11-14), viral infections (molluscum contagiosum, warts, herpes simplex, hepatitis B and C) (15-17), and fungal infections (sporotrichosis, dermatophytosis) (18,19)...

BackgroundCutaneous reactions to tattoos are most commonly granulomatous or lichenoid.PurposeWe describe a woman who developed a lymphocytic reaction following a cosmetic tattoo procedure with black dye. The reaction occurred not only at the site of the tattoos (eyebrows and eyelash lines), but also in non-tattooed skin (bilateral malar cheeks).Methods and MaterialsWe reviewed PubMed for the following terms: cosmetic, dye, granuloma, granulomatous, lichenoid, lymphocytic, perivascular, pigment, pseudolymphoma, reaction, and tattoo...

Acral pseudolymphomatous angiokeratoma of children (APACHE) is a rare form of cutaneous pseudolymphoma characterized byangiomatous papules with a predilection for the acral regions of children. Classically, a dense dermal lymphocytic infiltrate composed of both T and B cells is seen in histological specimens, together with prominent vessels lined by plump endothelial cells. Increasing evidence suggests that this condition is neither necessarily acral, pseudolymphomatous, nor angiokeratomatous. It may not always be a pediatric disease...

Small innocuous growths on the face usually do not pose difficulty in diagnosis on histopathology. However, some benign inflammatory lesions might mimic malignancy and hence need further investigations for final diagnosis. The distinction between a benign/inflammatory/malignant lesion needs no emphasis as the treatment plan, prognosis and the patient's well-being depends on it. Lymphocytoma cutis, or Spiegler-Fendt Sarcoid, is classed as one of the pseudolymphomas, referring to inflammatory disorders in which the accumulation of lymphocytes on the skin resembles, clinically and histopathologically, cutaneous lymphomas...
