2007;34:939-41. Kanitakis J, Audeffray D, Claudy A. Squamous cell carcinoma of the skin complicating lupus vulgaris. Another prospective study attempted to capture a broader cohort of patients by evaluating 411 consecutive pediatric patients presenting to a hospital emergency department with both fever and petechiae.3 Of the 53 ill-appearing patients (“toxic appearance”, inconsolable crying or screaming, or lethargy), 6 had invasive bacteremial infection while none of the 357 well-appearing children had positive blood cultures or cerebrospinal fluid bacterial cultures. Bilirubin accumulates in the tissues, especially those with a high elastin content (the skin and especially the sclera) (Sarkany et al., 1993). Histologically, there is a prominent lymphoplasmacytic infiltrate in an edematous ulcer bed with prominent capillary proliferation containing swollen endothelial cells. Early studies that focused on hospitalized children reported an incidence of meningococcal disease of 7% to 11% among children with fever and petechiae and a case-fatality rate of 10%.6 In the past few decades in North America, bacterial causes of fever and petechiae have been relatively uncommon.7,8 In a retrospective review of 129 hospitalized children with fever and petechiae, 20% had culture-proven bacterial infection, with 11% due to N. meningitidis and 6% due to Haemophilus influenzae type b.9 Almost 60% of cases were attributed to viral causes. Aside from a description of the rash and its evolution and the events surrounding its appearance, questions regarding recent illnesses or medication use should be asked. 47.1). The incidence of all forms of cutaneous tuberculosis, including lupus vulgaris (the most common form) decreased progressively in developed countries during the twentieth century, this change being attributed to improved living standards and specific therapy. 47.3). AVAs have been demonstrated using direct operative microscopic dissection by Schalin211 and Gius.205 Indirect support of this theory has been provided by evaluating the oxygen content of varicose blood and skin temperature over varicose veins.212–216 These studies estimate that AVAs occur in 64% to 100% of patients with varicose veins. Chancroid is treated with antibiotics. The incidence of this complication was estimated to be 10% in the early 20th century; however, a review of the literature revealed only a few cases in recent times 5-7. Lupus vulgaris is a chronic and progressive form of secondary cutaneous tuberculosis that occurs in tuberculin-sensitive patients. Special culture medium is required for isolation. The roof may rupture, forming a thin crust.

There have been occasional reports of various types of cutaneous malignancies developing on lupus vulgaris lesions 8. Fungal organisms may be visualized with the use of potassium hydroxide (KOH) on various microscopic preparations or with periodic acid–Schiff (PAS) and methenamine silver stains.2-6, Trichomycosis pubis and axillaris is an asymptomatic colonization of hair follicles by various corynebacteria (particularly Corynebacterium tenuis), which can lead to a red, cream, yellow, or, less commonly, black coating around pubic or axillary hairs and produce an offensive odor.

47.2).41 The clinical lesions follow autoinoculation of the mucocutaneous surface from underlying active TB with abundant organisms.

47.4A–D). Thus, a febrile patient with petechiae who is well-appearing, has normal laboratory workup, petechiae above the nipple line, and documented streptococcal pharyngitis has low risk of invasive bacterial disease. Keywords: Carcinoma; Skin cancer; Tuberculosis, cutaneous. Histopathological findings include granulomatous perifolliculitis and involvement of sweat glands by granulomatous inflammation.59 Lichen scrofulosorum has been documented following the administration of BCG and in patients with AIDS.60,61, Nodular tuberculid shows clinicopathological features of EIB and PNT.12 The skin lesions comprise a few to many dull red or bluish-red, and non-tender nodules of approximately 1cm in diameter that show a preference for the legs in children (Fig. Ziehl–Neelsen stain typically shows sparse bacilli.

From: Comprehensive Pediatric Hospital Medicine, 2007. They may be treated more effectively with the pulsed dye laser or intense pulsed light (IPL) sources (see Chapter 13). The pathophysiologic mechanism is not proved, but the high incidence of spider angiomas in alcohol-associated hepatitis and pregnancy suggests that elevated levels of estrogens, due to higher production or decreased metabolism, is responsible. Eventually, what are referred to as stellate abscesses form; these are suppurative foci that have coalesced and are surrounded by epithelioid cells and multinucleated giant cells.4,29, Culture of the lesions is the best method to identify the organisms in oculogenital chlamydial infections. The obligate intracellular organisms can typically be identified in vacuoles of vacuolated macrophages.32 The organisms stain faintly blue with hematoxylin and eosin (H&E), are gram-negative, and can be identified with Warthin-Starry stain. The appearance of new nodules within previously atrophic or scarred lesions is characteristic. Figure 1. It is impossible to determine the importance of this specific risk factor alone; however, the present case underlines the importance of risk factors for skin cancer, as well as other problems associated with a disease that has almost been forgotten, thus often resulting in misdiagnosis. Sensations were intact. USA.gov. Haller D, Reisser C. Lupus vulgaris manifestation as a destructive nose and facial tumor.

A family history of skin fragility, poor skin healing, wide disfiguring scars, increased bruising, anemia, hemophilia, or collagen vascular disease should prompt an evaluation for hereditary disorders that predispose to bleeding and cutaneous purpura. In some cases of erythema induratum of Bazin and papulonecrotic tuberculid, necrotizing vasculitis is present.24,25 The epidermis may be atrophic, hyperplastic, or ulcerated.

However, Ziehl–Neelsen stain of tissue sections will usually show numerous acid-fast bacilli. Culture was negative. Routine laboratory tests were normal except for an above-normal erythrocyte sedimentation rate of 32 mm/hour. Another important factor that may lead to increased venous pressure in cutaneous veins is the opening of arteriovenous communications.

Lymph nodes show accumulation of neutrophils, often with prominent necrosis, particularly in the early stages of the infection. The Internet Journal of Dermatology [Internet]. Proctocolitis may occur.3,4,29, A third stage comprises various sequelae from inflammation and includes fistula formation, fibrosis, and scarring.3,4,29,31 This may be complicated by sinuses and tracts between the skin and urethra and deforming scars of the penis. Chancroid is transmitted by sexual contact during the active phase of lesions, which in untreated patients lasts approximately 6 weeks. In the vast majority of cases, spider veins connect to underlying varicose veins either directly or through tributaries (Fig. Cutaneous involvement by M. tuberculosis can follow direct inoculation of organisms from an exogenous source; direct spread of organisms from an endogenous source such as tuberculous lymphadenitis extending to the skin (scrofuloderma) or autoinoculation, e.g. In 80% of patients, there is a diffuse, nonpruritic, papulosquamous eruption.
