Lichen planoporitis: keratosis lichenoides chronica revisited

We report a 70-year-old woman who over a 7-year period developed a widespread violaceous, reticulate and striate eruption with a keratotic component in a clinical pattern previously described as keratosis lichenoides chronica. Multiple biopsies showed a lichenoid reaction centred over the acrosyringium and eccrine ducts entering the epidermis. The acrosyringeal ducts were surrounded by an epidermis that was associated with saw-tooth acanthosis. The ducts displayed hypergranulosis and keratin plugs that extended into the stratum corneum. In the upper dermis the eccrine ducts showed squamous metaplasia with liquefaction of degeneration of their basal cells as well as apoptotic keratinocytes. The subepidermal acrosyringial zone and the eccrine ducts were associated with lymphocytic inflammation and fibrosis. These histopathological findings may represent the counterpart of lichen planopilaris targeting the eccrine ducts. The clinical features defining keratosis lichenoides chronica probably represents a heterogeneous group of conditions including this distinctive subset of lichen planus which we have termed lichen planoporitis.     

Mycosis fungoides presenting as keratosis lichenoides chronica

We report a patient with a 17-year history of reticulated keratotic papules on the trunk and limbs, and telangiectatic eruption on the face, in whom the diagnosis of keratosis lichenoides chronica was first established. However, the biopsies showed an epidermotropic infiltrate of small irregular CD4 + lymphocytes, and detection of a T-cell clone in the lesions by polymerase chain reaction confirmed the diagnosis of mycosis fungoides. Thus, keratosis lichenoides chronica can be an unusual and potentially misleading presentation of mycosis fungoides.     

Pediatric onset keratosis lichenoides chronica: a case report

Keratosis lichenoides chronica (KLC) is an acquired keratinization disorder that is rare in childhood. We report a case of sporadic pediatric-onset KLC with seborrheic dermatitis-like lesions on the forehead, papules in a retiform pattern in the axillae and mons pubis, and eye and oral mucosal involvement,with additional features of premature canities and a transient photosensitive eruption.     

Erythema ab igne with features resembling keratosis lichenoides chronica

Erythema ab igne (EAI) is an asymptomatic dermatosis that develops in response to chronic exposure to low‐grade heat. Characteristic findings on histopathology include epidermal atrophy, dermal elastosis, atypical histiocytes, and melanin and hemosiderin deposition. Reactive endothelial changes and prominent vascular proliferation are variable. Keratosis lichenoides chronica (KLC) is a rare lichenoid hyperkeratotic dermatosis. Acanthosis with parakeratosis and a lichenoid interface dermatitis with lymphocytes, histiocytes, and plasma cells are characteristic findings of KLC. Although its etiology remains unclear, KLC has been reported to occur in response to heat. Herein, we report a case of EAI with features resembling KLC.     

Case of keratosis lichenoides chronica with atypical sarcoidal granulomatous inflammation

Keratosis lichenoides chronica (KLC) is a rare chronic disease characterized by violaceous, papular and nodular lesions typically arranged in a linear and reticulate pattern. The etiology of KLC is unknown, but it may be associated with internal diseases such as hypothyroidism, glomerulonephritis and lymphoproliferative disorders. Herein, we describe the case of 44-year-old male patient with characteristic lesions of KLC on the trunk and extremities, present for 12 years. The clinical diagnosis was proven by histopathological examination on several occasions. In the years following the diagnosis of KLC, he developed bilateral hilar and multiple mediastinal, cervical and inguinal lymphadenopathies and hepatosplenomegaly. In 2000, diffuse interstitial and then reticulonodular pulmonary infiltrates associated with fever, weight loss, malaise and subcutaneous nodules developed. Biopsies taken from peripheral and mediastinal lymph nodes, pulmonary parenchyma, pleural tissue, bone marrow and skin showed non-necrotizing granulomas, indicating a sarcoidal granulomatous reaction. Characteristic histopathological findings and the absence of atypical cells, clonality and a high proliferative index excluded lymphomas. Furthermore, detailed tests showed no evidence of an infectious granulomatous disease. As far as we know, this is the first reported case of KLC associated with a sarcoidal granulomatous reaction.     

Easy to diagnose, difficult to treat: keratosis lichenoides chronica

Keratosis lichenoides chronica (KLC) is a rare disease, with approximately 70 cases reported in the literature. The problem in this long-lasting disease is generally the treatment, not the diagnosis. In the literature, many treatments failed to show any beneficial effect. We present a 20-year-old man with KLC that was successfully treated with a combination of phototherapy, acitretin and calcipotriol ointment. The patient's lesions showed a marked improvement with this combination. To our knowledge, this is the first report of this type of combination treatment being used successfully in KLC. This approach might help reduce doses of retinoids or psoralen ultraviolet A required when these are used separately, and limit the potential toxicity of these treatments.
