We report a case of hereditary trichilemmal cyst with proliferating trichilemmal tumor in a 64-year-oid man, who has generalized 157, variable sized firm cutaneous nodules for 40 years. The cystic nodules are chiefly located on the scalp and trunk which showed characteristic histopathologieal findings of trichilemmal cyst and proliferating trichilemmal tumors. His son also has multiple trichilemmal cysts and his mother seems to have had clinically similar lesions. The patient and his son were treated with surgical excision and therapeutic trial of oral isotretinoin for 2 months. Isotretionoin was ineffective in the patient, but the lesions of his son were decreased in size.

INTRODUCTION: Lichen Planus Pigmentosus (LPP) is a pigmentary disorder of unknown etiology, presenting with CASE REPORT: We report a case of a 32-year-old healthy male with widespread lichen planus pigmentosus, treated with clobetasol dipropionate 0.05% ointment, tacrolimus 0.1% ointment, and lowdose isotretinoin (0.1 to 0.2 mkd) showing a decrease in the progression and hyperpigmentation of patches and plaques after six months. CONCLUSION: Based on our case and recent studies, low-dose oral isotretinoin, in combination with topical tacrolimus and topical corticosteroids, may show promising outcomes in treating cases of widespread lichen planus pigmentosus.

Introduction: Rosacea is a chronic relapsing inflammatory facial dermatosis often characterized by flare-ups and remissions exclusively affecting the centrofacial skin. Case report: This is a case of multiple symmetric intensely erythematous papules, pustules, and plaques over both cheeks in a 47-year-old Filipino female. Dermoscopy showed brown-yellowish structureless areas, straight vessels in a polygonal pattern, dilated follicles, follicular plugs, ill-defined white rosettes, and non-specific scales. Skin punch biopsy showed spongiosis of the epidermis and demodex folliculorum within the follicular infundibulum. The dermis revealed telangiectasia of blood vessels and dense inflammatory infiltrates. Hypertrophy of sebaceous lobules was also seen. The patient was initially treated with oral lymecycline 300mg twice a day for 2 weeks without improvement. Due to the persistence of centrofacial erythema, papules and pustules, the patient was given prednisone 10mg once a day for 1 month and low dose isotretinoin 10mg once a day for 8 months which resulted in significant decrease in erythema and number of existing lesions. To further decrease the inflammation con- tributed by demodex mites, permethrin 5% cream twice a day for 1 month was applied. Long-pulsed Neodymium-doped yttrium aluminum garnet (Nd:YAG) 1064 nm laser for a total of 10 sessions together with Isotretinoin 10 mg every other day effectively maintained remission for 1 year and 5 months. Gentle skin care measures, sunscreen, metronidazole 0.75% cream once a day, and desonide 0.05% cream twice a day for 1 week in cases of acute flares were maintained during the treatment course. Conclusion An armamentarium of topical and oral antibiotics, corticosteroids, isotretinoin and non-ablative long-pulsed Nd:YAG 1064 nm laser showed significant improvement in the inflammatory papules, pustules, and centrofacial erythema of rosa- cea and proves to be beneficial in the maintenance of its long-term remission.

Epidermolytic Ichthyosis (EI) is a rare non-syndromic keratinopathic ichthyosis without definitive treatment. This is a case of EI in a 5-year-old Filipino female who presented with hyperkeratotic scales sparing the palms and soles. Histopathology revealed epidermolytic hyperkeratosis. A trial of treatment with isotretinoin 0.3 mg/kg/day, together with keratolytic agents, urea lotion and lactic acid lotion, resulted in a marked decrease in the thickness of the scales and odor. Interestingly, rebound effects were noted at 0.6 mg/kg/day. Taking into account that EI presents with more skin fragility compared to non-EHK ichthyosis, the authors surmise that there may be a smaller treatment window for patients with EI, which is notably lower than recommended for ichthyosis in general.

INTRODUCTION: Rhinophyma, aside from persistent centrofacial redness is a major diagnostic criteria for rosacea. Phyma may be mistaken for hypertrophy of tissue due to an underlying hemangioma. CASE REPORT: A 35-year-old female presented with few erythematous papules on the face and nose 19 years prior to consult. Lesions evolved into multiple erythematous nodules on nose and was mistaken for tissue hypertrophy due to an adjacent congenital hemangioma. Her hemangioma was treated with pulsed dye laser 16 years prior with noted decrease in size and erythema. Recently she noticed enlargement of her nose with persistent redness. She presented with multiple firm, thick irregularly shaped erythematous nodules with prominent pilosebaceous pores and telangiectasia on the nose. Skin punch biopsy was done which revealed hypertrophy and lysis of sebaceous lobules with a moderately dense inflammatory infiltrate of lymphocytes. Histopathological diagnosis was rhinophyma. Patient was treated with low dose isotretinoin (0.20 mkd) with marked flattening of lesions in just one month. CONCLUSION: Distinguishing phyma from tissue hypertrophy caused by hemangioma poses as a diagnostic challenge. Careful dermatological examination and histopathological findings will aid in correct diagnosis. Low dose oral isotretinoin is an effective treatment for rhinophyma.
