We report a case of an 11-year-old girl who presented with a gradually enlarging verrucous plaque on the left knee for 3 years. Physical examination showed a solitary, slightly erythematous, scaly, verrucous plaque on the left knee measuring about 1.5 cm x 2 cm. Biopsy revealed granulomatous dermatitis consistent with cutaneous tuberculosis. A diagnosis of tuberculosis verrucosa cutis (TBVC) was made and anti-tuberculous therapy was initiated consisting of rifampicin, isoniazid, pyrazinamide and ethambutol for 2 months followed by rifampicin and isoniazid for 4 months. Upon completion of therapy, only a slightly atrophic scar remained, supporting our diagnosis. This report highlights TBVC must be considered in patients with chronic skin lesions in countries with high prevalence of tuberculosis.

Introduction: Geriatric health has become a major issue worldwide. According to the World Health Organization(WHO), between 2015 and 2050, the proportion of the world's population over 60 years will nearly double from 12% to 22%. There is paucity of literature involving the spectrum of frequencies of Filipino geriatric dermatoses. Objectives: To report on sociodemographic and clinical profiles of geriatric patients seen at the department of Dermatology of Southern Philip- pines Medical Center from January 2016 to December 2019. Methods: A retrospective descriptive study was conducted. Sociodemographic and clinical parameters were recorded and analyzed. Descriptive statistics such as frequencies and percentages were used. Results: Study population involved 470 patients with 372 out-patients and 98 in-patients. There was a preponderance of elderly patients with ages of 70-79 and a slight female predominance. Most were married, residents of Davao City, retired or unemployed and had no vices. About 711 derma- tologic dermatoses were recorded. Majority of concerns(22.08%) were classified under allergic and eczematous disorders. A greater number of cases were managed by a combination of topical and oral medications. A proportion of these patients(38.09%) had at least one known co-morbid condition; most common of which is hypertension. The top 10 most common dermatoses include (1)xerosis, (2)contact dermatitis, (3)lichen simplex chronicus, (4)dermatophytosis, (5)stasis derma- titis, (6)seborrheic dermatitis and seborrheic keratosis, (7)acrochordon, (8)psoriasis vulgaris, (9)herpes zoster and (10)verruca plana. Conclusion Geriatric dermatology is an emerging branch in the new millennium. Raising the level of awareness about these dermatoses may be crucial in proper management and improved quality of life for Filipino elderly patients.

Subepidermal blistering disorders (SBD) are diseases associated with antibodies that attack structural proteins of the skin. Blister formation with widespread distribution is common in these diseases. Diagnosis of SBD is established through the demonstration of immunoglobulin deposits in the dermoepidermal junction by direct immunofluorescence microscopy, and through the presence of circulating autoantibodies by serology. Systemic corticosteroids and other immunosuppressive drugs are used to treat SBD. We present the case of a 16-year old female with a 6-week history of intensely pruritic, erythematous plaques with generalized blister formation on the face, trunk, upper extremities, and inner thighs. We diagnosed the patient as having a subepidermal blistering disorder. We placed her on a course of prednisone and azathioprine, which successfully treated her lesions.

Introduction: Cushing syndrome caused by application of topical corticosteroids is rarely reported. Systemic side effects like suppression of hypothalamic-pituitary-adrenal axis, growth retardation in children and iatrogenic Cushing syndrome can occur even in small doses of potent topical steroids.1 Case Summary: This is a case of a 3-month old female who was referred to our department due to generalized erythema with desquamation. History revealed that the patient had recurrent eczema and the mother applied an over-the-counter medication containing Ketoconazole+Clobetasol 10mg/500mcg per 7-gram cream thrice daily for ten weeks. The estimated topical steroid applied weekly was around 8.5 grams and at time of admission, the patient had been exposed to approximately 50 grams of a potent topical corticosteroid. The patient presented with fever, irritability, and had positive Nikolsky sign thus managed as a case of staphylococcal scalded skin syndrome associated with topical steroid – induced iatrogenic Cushing syndrome. Unfortunately, patient’s condition worsened and with progressive pneumonia, she expired on the 23rd hospital day. The fatal outcome was due to SSSS which was complicated by progressive pneumonia and topical steroid – induced iatrogenic Cushing syndrome. The complex interplay of these features eventually led to sepsis and death. Conclusion This case highlights the risks related to abuse of potent steroid-containing preparations and the importance of education to prevent severe and catastrophic outcomes of injudicious steroid use.

Acral lentiginous melanoma (ALM) is the rarest of the four subtypes of cutaneous melanoma.1 It accounts for only 2-8% of melanomas in caucasians.2 Only 52 cases of ALM have been recorded in the Philippine Dermatological Society Health Information System from 2011 to 2016.3 Histopathologic demonstration of cytologic atypia, presence of mitoses in the deep dermis, pagetoid spread of epidermal melanocytes and lack of maturation of nests with descent into the dermis are features diagnostic of melanoma.2 4 ALM is primarily managed through wide surgical excision. The most common sites for ALM are the soles, palms, and subungual areas.2 The rarity of ALM, the inconspicuousness of the locations of some lesions, and the difficulty in discerning ALM from benign lesions and traumatic changes usually delay the diagnosis and contribute to the poor prognosis of the disease.4 5 6 A 53-year-old male consulted us for an enlarging pigmented plaque on the sole of his left foot. The lesion started as a junctional nevus, which the patient had since birth. The nevus, originally measuring approximately 0.5 x 0.5 cm, started to increase in size one year prior to the consultation. One month before consultation, the patient noted a black nodule on the center of the lesion. A week before consultation, the lesion bled and became painful after manipulation by the patient. Dermatologic examination of the plantar aspect of the left foot revealed a 1.7 x 1.6 cm, dark brown-black, asymmetric plaque with cobblestone-like surface and a black indurated nodule on the center (Figure 1A). Dermoscopic findings of bluish white veil and irregular pigmentation with variable hypopigmented blotches are suggestive of acral melanoma (Figure 1B). Skin punch biopsy and immunohistochemical stains for S100, Melan A, HMB-45, and KI-67 confirmed the diagnosis of ALM (Figure 2, 3). We did a wide local excision of the lesion with a 2-cm margin from the tumor edge, with depth up to the suprafascial level (Figure 4A). The excisional defect was repaired with a split-thickness skin graft taken from the patient’s skin on the right thigh (Figure 6), which provided excellent aesthetic result. We also did a sentinel lymph node biopsy on the left inguinal area (Figure 5A,B). Frozen section biopsy showed solid nests of atypical melanocytes invading the surrounding fibrous stroma. Individual cells exhibit round to oval, deeply basophilic nuclei and abundant, clear to eosinophilic cytoplasm. Some areas showed prominent melanin pigmentation. Sections along lines of resection, lymphovascular channels, nerves and adipose tissues of the excised mass (Figure 4 B,C) and lymph nodes from sentinel biopsy were all devoid of malignant tumor cells. Histopathologic findings from frozen section biopsy and permanent section biopsy were both consistent with malignant melanoma with 3 mm Breslow thickness. The patient’s postoperative course, including wound healing, was uneventful (Figure 7). During the patient’s 12-month follow up period, we did not observe any signs of local or distant recurrence of the tumor.
