Background: Hidrocystoma is a rare benign swelling(tumour) of sweat glands also known as the cystic form of hidroadenoma, cystadenomas, sudoriferous cysts, and Moll’s gland. It has no racial or sex predilection. Its rarity and site of occurrence makes its management challenging due to limitation in knowledge of making diagnosis, treatment, availability of drugs and interventions and aesthetic concerns. Presentation of Case: A 35 year old Nigerian woman from the Igbo ethnic group with tertiary level of education who presented to the dermatology outpatient clinic with a 10 year history of recurrent peri-orbital swelling associated with occasional pruritus. There was no history of similar lesion in any family member. Patient had resorted to self-medication and consulted different doctors prior to being referred to the dermatologist. Her physical examination was normal. She was also counselled about the disease and management options. She subsequently received seven sessions of the chemo-ablation using trichloroacetic acid (TCA) with remarkable improvement and has had no recurrence of lesions for the past 1 year. Conclusion: Hidrocystomas can be successfully treated in our environment.

<p>Psoriasis is uncommon in this part of the world, and the pustular variety is even rarer. It is for this reason that the patients are frequently misdiagnosed by their health care providers and presentat late to the dermatologists when complications have already set in. We report a case of a 33 year old female who presented to us with a two year history of pustular eruptions on her hands and feet, pain and swelling of joints in the affected areas and subsequent development of deformities. Prior to her presentation, she has been misdiagnosed as having tuberculosis of the skin as well as leprosy in different hospitals and treated as such with no improvement. On presentation to us, a skin biopsy was done and the specimen sent for histopathology. A diagnosis of pustular psoriasis was made and she was placed on oral methotrexate. She responded to treatment and the lesions resolved in a few weeks except for the joint deformities. This case illustrates the challenges encountered by patients with psoriasis in a resource poor setting like ours as well as the importance of availability of affordable drugs like methotrexate in their management. This is so considering the high cost and non-availability of more modern biologic agents in this part of the world.</p>

Background: Immunosuppression due to various etiologies has been associated with the occurrence of dermatophytosis. Several studies in the past have demonstrated that Human Immunodeficiency Virus (HIV) infection is a risk factor for the acquisition and severity of dermatophytosis. This study examined the prevalence and clinical variations of dermatophytosis amongst HIV positive patients seen in Port-Harcourt, Southern Nigeria. Methods: Between July 2019 and 2020 173 seropositive cases and 173 seronegative controls were recruited for this study. They were interviewed with a structured questionnaire and thereafter screened for the presence of dermatophytosis and sent for mycology studies. Results: There was a higher prevalence of dermatophytosis in the HIV seropositive group when compared to the control group. Most of the lesions seen were not markedly different from that seen in immunocompetent persons. 41.65% of the cases were found among those with CD4 cell counts below 200. Tinea corporis was the commonest lesion seen (50%).  Trichophyton species was the commonest dermatophyte isolated, followed by Microsporum spp. Conclusion: Prevalence of dermatophytosis is significantly higher in HIV infected patients and commonly occurs in advanced stages of the disease. Tinea corporis is the most common lesion in this group of patients and Trichophyton spp. a common causative agent.
