However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates: automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or upon express reinstatement by the Licensor. For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. Section 7 – Other Terms and Conditions.

To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.

An Unusual presentation of Cutaneous Sarcoidosis in a Nigerian: A case report
Abstract
Background: Sarcoidosis is an idiopathic disorder which present with different manifestation. This is an unusual case of cutaneous sarcoidosis with extensive polymorphic lesions on the skin as the only organ involved.
Case Report: Mrs. A.O, a 28 year old house-wife presented with a one year history of progressive itchy, reddish, raised skin rashes for one year. Lesions were initially localized to the chest and limbs but subsequently involved the whole body including the palms and soles. No history of fever or weight loss. On examination, she had generalized erythematous, annular and arcuate plaques with areas of active edges involving the whole body including the palms and soles. Healed lesions were atrophic and hyperpigmented (Figure 1). No mucosal involvement. Her chest radiograph, FBC, ESR, LFT, serum Calcium, ACE levels (20U/L) and ECG were normal, while her Mantoux and Gene expert test was negative. Biopsy of the lesion showed dermal infiltrates, composed of epithelioid histocytes disposed in nodules as well as multinucleated giant cells of langhans and foreign body types features consistent with cutaneous annular sarcoidosis (Figure 3 and 4). She was placed on systemic steroids followed by topical steroids and made significant improvement. (figure 2)
Conclusion: Sarcoidosis is not common in our environment and cutaneous manifestation as the sole presentation is even rarer. We report one such case with skin as the sole organ affected and equally of interest is the extensive nature of the lesions observed.
