INTRODUCTION: Cutaneous involvement is relatively uncommon representing a small fraction (1-2%) of the localizations of extrapulmonary tuberculosis. Cutaneous TB presents with several clinical forms, wherein one of the most common is scrofuloderma resulting from the direct extension of a tuberculous focus from a deeper structure such as the lymph node into the overlying skin. Tuberculous gumma is a rare form which occurs due to hematogenous spread of the TB bacilli. Although presenting with a wide clinical spectrum, it is believed that the association of different morphologies as well as numerous lesions and sites of cutaneous TB in a same patient is very rare.

CASE REPORT: This is a case of a 20-year-old Filipino male presented with a fi ve-month history of several progressive cutaneous lesions initially presenting as subcutaneous nodules evolving into well-demarcated suppurative painless ulcers which were unresponsive to topical antibiotic. Skin punch biopsy from the medial malleolar area of the right foot revealed dilated blood vessels with a diffuse inflammatory infiltrate of lymphocytes, histiocytes, and few multinucleated giant cells. Clinical and laboratory findings were consistent with cutaneous tuberculosis. Patient was started on anti-Koch's treatment regimen and presented an excellent response to treatment showing resolution of the skin lesions on the neck and forearms and notable regression of the lesions on the right foot within four (4) months.

CONCLUSION: This case serves as a reminder that cutaneous tuberculosis can manifest with a wide spectrum of clinical presentation which can mimic diverse dermatological conditions and may present with high rates of negative or equivocal diagnostic testing results. This report highlights the importance of a high index of suspicion in the timely diagnosis and management of tuberculosis in countries wherein tuberculosis remains a significant health burden such as the Philippines.

Summary Tuberculosis (TB) is a serious communicable disease of major concern in endemic regions. Cutaneous tuberculosis (CTB), which accounts for less than 1% of all cases, can cause severe infection in susceptible patients. The diagnosis of CTB is challenging as it can present with a multitude of clinical presentations. The diagnosis must be supported by highly sensitive and specific investigations. This paper highlights the susceptibility of immunocompromised patients to the development of CTB and the challenges in making a diagnosis.

BACKGROUND: Although one hair usually arises from a single follicular opening in normal healthy subjects, we can see two or more hairs emerging from the single opening through close inspection. The latter is called "compound hair", described by Lowenthal in 1946, however, few reports on this have been made since. Histopatholoigcally two or more hairs which have an independant external root sheath arise from one follicular opening like its clinical appearance. We examined the distribution and density of compound hair in order to define its difference according to anatomical sites and aging process. OBJECTIVE AND METHOD: We counted the number of hairs in the circle(2 cm in diameter) at te frontal, temporal and occipital scalp of 24 old young men(22.5+/-2.0 years old) and 24 old men(64.4+/-12.9 years old), respectively. RESULTS: The summated number of grouped hair, which was mostly regarded at compound hair, was greater in the young group than in old group in the frontal area, but was smaller in young group than in old group in from the temporal and occipital areas. The proportion of grouped hair to total hair in the older group was lower in the frontal area, but higher in the temporal and occipital areas(p<0.05, p<0.01) according to aging process, however, no significant change was seen between the frontal area and the sum of single hair to compound hair was significantly decreased in the temporal and occipital areas(p<0.05, p<0.01) according to aging process, however, no significant change was seen between the frontal area and the sum of the three tested areas. CONCLUSION: Compound hairs are observed frequently on the scalp of normal healthy subjects and are most frequently seen on the occipital scalp in both of the young and old.

For a definitive diagnosis of cutaneous tuberculosis, the demonstration of the mycobacteria is essential, but routinely available methods such as AFB stain and culture have poor sensitivity and are time-consuming. Recently, PCR has emerged as a promising tool in the diagnosis of cutaneous tuberculosis due to its high sensitivity and speed. We herein report a case of tuberculosis verrucosa cutis without demonstarable acid-fast bacilli, but diagnosed by using PCR.

Summary Eosinophilic granulomatosis with polyangiitis (EGPA), or Churg-Strauss Syndrome (CSS) is a rare granulomatous necrotizing vasculitic disease characterized by the presence of asthma, sinusitis, and hypereosinophilia. We describe a patient who was initially diagnosed with tuberculous lymphadenitis and later diagnosed with EGPA.

A 33-year-old male had a 22-year history of generalized xanthogranulomas but had a normal lipid profile. He also developed ulcerating plaques on his arm and back that were consistent with cutaneous tuberculosis on histopathologic and polymerase chain reaction PCR studies. In a normolipemic patient with generalized xanthogranulomas, a reactive granulomatous response of histiocytes to infection is explored since these share a common CD 14+ precursor with the macrophages that are vital in tuberculosis.

Tuberculosis verrucosa cutis is a common form of cutaneous tuberculosis. Most cases of tuberculosis verrucosa cutis appear as secondary infections of skin, however concomitant primary internal organ involvement rarely occurs. To our knowledge, only three cases of coexistence of tuberculosis verrucosa cutis and pulmonary tuberculosis have been reported in literatures to date. We report on another case of tuberculosis verrucosa cutis, which occurred in a middle-aged, Korean woman with pulmonary tuberculosis, and review the literatures.
