Lupus vulgaris (LV) is a type of paucibacillary cutaneous tuberculosis that can occur due to inoculation, lymphatic, or hematogenous route. It occurs in a previously sensitized individual with high immunity to tuberculosis. LV can have different morphology of presentation, which can lead to difficulty in diagnosis. The Tuberculin test is strongly positive. Histopathology will show epithelioid granulomas in the superficial dermis and acid-fast bacilli rarely demonstrable within the granulomas. Dermoscopy will show focused linear vessels on a yellow to orange background. Culture is the gold standard for diagnosis, but its positivity rate is low. Mycobacterium tuberculosis bacilli can be detected using polymerase chain reaction from the lesions. Histopathology, tuberculin test, dermoscopy, molecular test, and culture would help diagnose LV. This review discusses the introduction, pathogenesis, clinical features, differential diagnosis, investigations, complications, and treatment of lupus vulgaris in detail. This review can help the dermatologist understand the condition better with appropriate diagnosis and therapy.

Cutaneous tuberculosis is a rare type of extrapulmonary tuberculosis and it is uncommon even in places where tuberculosis is widespread. A 32-year-old female presented with fever and headache along with prior history of an ulcer in her leg which was treated as cellulitis at another centre. The neck rigidity, and the Kernig and Budzinski sign were also positive. There were also features of increased intracranial pressure. The non-contrast computed tomography showed bilateral hydrocephalus and hypodense areas. She was managed for increased intracranial pressure and anti-tubercular therapy for disseminated tuberculosis. Biopsy of non-healing wounds should be checked for lupus vulgaris. Keywords: case reports; lupus vulgaris; meningitis; skin; tuberculosis.

Cutaneous tuberculosis represents the fifth extrapulmonary form in Morocco after pleural, lymph node, urogenital, and intestinal tuberculosis. It is recognized to form a continuous immunopathologic spectrum, ranging from a high intensity to a low intensity of cell-mediated immunity, which explains the multiplicity and heterogeneity of anatomo-clinical forms. Association of multiple forms in the same patient is really rare. In this regard, we report a case of scrofuloderma on axillary tuberculosis adenitis associated to a lupus vulgaris in an immunocompetent patient, which was confirmed by histology, QuantiFERON-TB Gold test, and polymerase chain reaction. He received an antituberculous therapy with clinical regression of the lesions. In conclusion, cutaneous tuberculosis is still endemic in developing countries.The diagnosis is difficult because of its clinical polymorphism. That's why it's should be suspected clinically in the presence of any destructive or verrucous skin lesion evolving without healing for a long period and confirmed by bacteriological examinations and histology.

Cutaneous tuberculosis (CTB) is an uncommon form of extra-pulmonary tuberculosis accounting for ≤2% of mycobacterium tuberculosis cases and is more often reported from developing countries. Tuberculid, a cutaneous hypersensitivity reaction to mycobacteria or its fragments, is a another rare cutaneous manifestation seen in association with tuberculosis of other organ systems including tuberculous lymphadenitis, pulmonary tuberculosis, etc. Co-occurrence of a tuberculid with CTB is extremely rare. Herein we report a childhood case of lupus vulgaris, a type of CTB, associated with an atypical presentation of tuberculid.

Cutaneous tuberculosis classically presents as Lupus vulgaris, scrofuloderma, tuberculosis verrucose cutis and tubercular abscess. Hypersensitivity reaction to the bacilli leads to Lichen scrofulosorum and papulonecrotic tuberculids. At the same time, it can have myriad of clinical presentations, many of which are still undescribed. It is important to regularly update ourselves with these unusual manifestations so as to ensure early treatment and reduction of overall morbidity. In this case series tuberculosis manifesting as rapidly progressing diffuse facial granulomas, sporotrichoid tuberculosis, tuberculosis mimicking squamous cell carcinoma, scrofuloderma as tubercular ulcer, lupus vulgaris with nasal septal perforation, lupus vulgaris resembling furuncle, psoriasis, dermatitis and BT Hansen are described in immunocompetent individuals. These cases highlight the importance of recognition of atypical forms of cutaneous tuberculosis to minimize scarring and dissemination of bacilli.

Cutaneous tuberculosis occurs in 1-2% of world cases of tuberculosis and more common in tropical countries. It presents with different clinical forms. Unusual clinical presentations are not uncommon and awareness of these will help in suspecting and managing these patients successfully. Lupus pernio like lupus vulgaris, tuberculosis of glans penis and lichen scrofulosorum on the distal parts of limbs are presented here because of their unusual clinical presentation.
