Derm Coding Consult Excellence in Pediatric Dermatology™ Keratinocytes, CD4+ and CD8+ lymphocytes, dendritics, mastocytes and macrophages play a role in pathogenesis of LP. In LP, keratinocytes are the target cells that undergo apoptosis. However, in order for the apoptosis to occur, these cells express an unknown antigen. When activated, keratinocytes secrete chemokines, which attract lymphocytes and other immune cells that aggravate LP and cause its chronicity. CD4+ lymphocytes produce interferon gamma, tumor necrosis factor-alpha (TNF-α) and interleukin 2, which are cytokines activating macrophages and CD8+ lymphocytes. Secretion of TNF-α is related to TNF-α receptor in target cells, and determines apoptosis of keratinocytes. TNF-α can enhance release of lymphocytes from blood vessels to peri-vascular areas. Moreover, it should be noted that production of TNF-α by macrophages can initiate apoptosis of basal keratinocytes and indirectly increase disintegration of basal membrane by matrix metalloproteinase 9 produced by T cells26. Receptors present in plasma membrane (integrins) interact with basal lamina proteins and can initiate a wide range of cell responses such as secretory processes. Thus, if membrane receptors change due to a series of environmental factors, their performance changes as well, even if other conditions are optimal (presence of ligand or proper agonist). Therefore, environmental changes such as increase in TNF-α in patients with LP can change the function of acinar cells in salivary glands. Thus, changes in signaling can change the organization of basal lamina and alter the process of Mucin 5B production in acinar mucosal cells10. Serous acinar cells present in the parotid gland do not produce mucin15. This explains the lack of a significant difference in the level of Mucin in stimulated saliva, because the main volume of stimulated saliva is secreted by the parotid glands and Mucin 5B is mainly produced by the sublingual and minor salivary glands27. In our study, Mucin 5B in unstimulated saliva was significantly lower in patients with OLP. The level of Mucin 5B in stimulated saliva was lower in OLP patients compared to healthy controls, but not significantly.

A 17-year-old male presented with a chief complaint of a burning sensation in his gums leading to difficulty in eating and swallowing for 6 months. The patient reported aggravation of the discomfort and sensitivity in the gingiva on consumption of acidic or spicy food and drinks. Local deposits were inconsistent with the corresponding lesion. No cutaneous lesions were visible.

Sulle papule del lichen ruber planus appare, generalmente, un reticolo biancastro: è un segno tipico della dermatosi, che permette il riconoscimento immediato. Le papule possono rimanere isolate oppure raggrupparsi formando veri e propri ammassi abnormi. Il problema principale, che ostacola la diagnosi, è dato dal grattamento consistente generato dalle papule: il soggetto affetto, attraverso lo strofinio, toglie la pellicola superficiale della lesione, impedendo il riconoscimento clinico.

R/ Protopic (tacrolimus) 0.03% zalf, tube à 30 of 60 g. Symptomatic oral LP can be treated initially with fluocinonide compounded in orabase or clobetasol gel. I found many patients will respond to this therapy nicely. It is easy and well tolerated. The use of dental trays for 15 minutes to help apply the medication to the involved gingival surfaces can be very useful. My next choice is the use of tacrolimus 0.03% ointment; if after 6 weeks of twice daily treatment does not help, I will increase to 0.1%. One must educate patients on the use of this medicine so that they are not taking what amounts to systemic doses.

Pimecrolimus has significant anti-inflammatory activity and immunomodulatory capabilities with low systemic immunosuppressive potential.[19,20]

Accessibility Recent Issues These are the most commonly used group of drugs for the treatment of OLP. The rationale behind their usage is their ability to modulate inflammation and immune response. They act by reducing the lymphocytic exudate and stabilizing the lysosomal membrane. Topical midpotency corticosteroids such as triamcinolone acetonide, high-potent fluorinated corticosteroids such as fluocinonide acetonide, disodium betamethasone phosphate, and more recently, superpotent halogenated corticosteroids such as clobetasol are used based on the severity of the lesion. The greatest disadvantage in using topical corticosteroids is their lack of adherence to the mucosa for a sufficient length of time. Although trials were done using topical steroids along with adhesive base, no study shows their superiority when compared to steroids without the base (carboxymethyl cellulose). However, the same study also recommends the usage of adhesive paste used for dentures, which contains only inactive ingredients as a vehicle to carry the topical application. This has shown excellent bioadhesive properties, due to its high molecular weight (above 100,000) and the flexibility of the polymeric chain. Small and accessible erosive lesions located on the gingiva and palate can be treated by the use of an adherent paste in a made-to-measure tray (custom tray), which allows for accurate control over the contact time and ensures that the entire lesional surface is exposed to the drugs. Patients with widespread forms of OLP are prescribed high-potent and superpotent corticosteroids mouthwashes and intralesional injections. Long-term use of topical steroid can lead to the development of secondary candidiasis which necessitates antifungal therapy. The potential tachyphylaxis and adrenal insufficiency is high when using superpotent steroids like clobetaso l, especially when used for a longer period of time. Systemic corticosteroids are reserved for recalcitrant erosive or erythematous LP where topical approaches have failed. Systemic prednisolone is the drug of choice, but should be used at the lowest possible dosage for the shortest duration (40–80 mg for 5–7 days).
