ABSTRACT
@#Pachydermoperiostosis (PDP) or primary hypertrophic osteoarthropathy (PHO) is a rare genetic disorder that affects mainly skin and bones. Its main clinical features are pachyderma (thickening of the skin), periostosis ~excessiv~ bone formation) and clubbing of fingernails. The d1sea~e is more common among males with a 7:1 ratio, starts during adolescence and stabilize and cease progression after 5 - 20 years.@*OBJECTIVE@#To discuss the summary of the case, new management options, and outcomes of the management options.@*CASE SUMMARY (METHODS)@#A 28-year-old male presents with a 9-year history of wrinkling of his facial skin. Other associated symptoms were seborrhea, acne, clubbed fingers, and occasional minimal knee joint pain. Histopathology results showed thickened dermis, fibrosis of the papillary dermis and around the folliculosebaceous units, hyalinized collagen bundles involving the fibrous trabeculae of the subcutis, and prominence of sebaceous and eccrine glands. The patient was given oral isotretinoin at 0.5 mg/kg/day, underwent fractional CO~ laser f?r rhytides and large pores, and given botuhnum toxin A injection (total of 16 U) on 5 sites at the glabellar region. The patient was referred to plastic surgery for frontal rhytidectomy, and orthopedic surgery for management of joint pains.@*RESULTS@#The patient noted 80% improvement from baseline.@*CONCLUSION@#Treatment of pachydermoperiostosis is mainly symptomatic and requires a multi-spec~alty approach. Because of its rarity, treatment options for pachydermoperiostosis have yet to_ be standardized. In this particular case, all available options in the institution were utilized which led to satisfaction of the patient of the outcome.
ABSTRACT
Introduction@#Methotrexate is being given by dermatologists in only extreme cases of skin disorders such as in severe Psoriasis Vulgaris. Strict precautionary measures are done to avoid its well-known adverse effects. An early but less common sign of its toxicity are painful erosions on plaques. Methotrexate is an effective but potentially toxic treatment for different severe dermatologic disorders such as in severe Psoriasis Vulgaris. Meticulous and complete history-taking, physical examination and laboratory work-up to come up with a correct diagnosis as well as, knowledge of indications for treatment, proper dosing, folate supplementa-tion, monitoring, proper referral and early detection of its toxicity are important in order to avoid cutaneous and systemic adverse effects including death. @*Case Report@#A case of a 57-year old male with a 2-day history of painful erosions on plaques on both upper and lower extremities after eleven days of taking Methotrexate 2.5mg/tablet one tablet three times a day without folate supplementation. He was then being treated by a general physician as a case of Psoriasis Vulgaris. He was subsequently admitted under the Internal Medicine service due to epigastric pain, nausea, anorexia, generalized body weakness and passage of black tarry stools. He was referred to the Department of Dermatology for the painful erosions on plaques. He expired two days after admission due to Acute Respiratory Failure. Post-mortem Skin punch biopsy was done and revealed chronic eczematous dermatitis consistent with Lichen Simplex Chronicus with superimposed drug induced hypersensitivity reaction.
