Efficacy of autologous stromal vascular fraction injection in the treatment of androgenic alopecia.

Androgenic alopecia (AGA) is a common condition associated with loss of terminal hair on the scalp in a specific pattern in both males and females. Management of AGA is usually challenging as the approved therapeutic options are limited. Our aim was to evaluate the efficacy of non-enzymatic stromal vascular fraction (SVF) as a new promising treatment for AGA. From April to December 2021, this prospective study included 30 patients with AGA who were enrolled from the University Hospitals' dermatology outpatient clinics. Patients received a single session of autologous SVF injection and were then followed up for 6 months. There was an increase in hair shaft caliber from 0.037 ± 0.01 mm before treatment with SVF to 0.056 ± 0.02 mm after 6 months of treatment. Also, hair count/cm2 increased from 130.87 ± 14/cm2 to 151.93 ± 22.36/cm2 and terminal to vellus hair ratio increased from 77.06 ± 10.47% to 81.45 ± 11.98% at the end of the study. No significant difference was recorded between male and female groups as regard response to treatment. We concluded that SVF is an effective line of treatment for AGA with significant improvement regarding hair density, hair diameter, global photography, and patient satisfaction.

Epidemiological and clinicopathological analysis of basal cell carcinoma in Egyptian population: a 5-year retrospective multicenter study.

PURPOSE: Basal cell carcinoma (BCC) is the most diagnosed type of cancer accounting for 80% of all keratinocyte malignancies. However, the exact demographic properties and clinicopathological criteria for BCC in Egyptians are not clearly reported. Our aim is to report and analyze the epidemiological and clinicopathological features of BCC in Egyptians. METHODS: We retrospectively reviewed the medical records for patients diagnosed pathologically with BCC during the period from January 2017 to December 2021. Data were recruited from four dermatology centers with different geographical distributions. RESULTS: We registered 544 patients. Their age ranged between 22-91 years with a mean of 61.6 ± 13.2 years. Females showed younger age of onset. The mean duration of the tumor was 3.9 ± 3.8 years. The most common involved region was the head (79.4%), and about one third of patients (32.2%) had a giant lesion (> 5 cm). The most common clinical presentation was ulcerative lesions (44.9%). Pathologically, the nodular type represented the most common variant (50.4%). CONCLUSION: Our results proposed that the annual incidence of BCC is increasing among Egyptians. Ultraviolet radiation is considered a high-risk factor of BCC leading to a higher affection of the head region and more prevalence in men. This study also highlights some criteria of BCC in Egyptians such as the long duration of the tumor, the early onset in females, the higher percentage of giant types, and the predominance of nodular type. To our knowledge, this is the first report describing the characteristic features of BCC among Egyptians.

Evaluation of safety and efficacy of topical 4% nicotinamide in treatment of psoriasis; among a representative sample of Egyptians (an analytical observational study).

To assess and evaluate the efficacy and safety of nicotinamide 4% topical formulation for the treatment of mild to moderate psoriasis. This study was conducted on 60 patients aged 18-65 years, with mild to moderate psoriasis vulgaris. Nicotinamide 4% in a cold cream base was used twice daily for 12 weeks. Nicotinamide 4% topical treatment shows satisfactory results, more in males than in females. Some patients report disturbing irritation (burning, itching, and redness) upon the usage of topical nicotinamide treatment and were advised to wash out the treated area after 1 h of cream application, which solved the issue. No other adverse effects of treatment were reported by patients during the study period. Unicentral base, a limited amount of sample size, and 12 weeks duration of therapy and follow-up period, which may not be sufficient to demonstrate the complete therapeutic properties and side effects of using nicotinamide as a long-term treatment for psoriasis. This study reveals statistically reliable evidence of the positive impact of topical 4% nicotinamide preparation used alone on the treatment of psoriasis with minimal side effects. Thus, we can conclude that topical nicotinamide preparation may be a good adjuvant to the current treatment regimens used alone or alternate currently used topical therapeutical regimens if used in combination.

The combined effect of CO2 laser, topical diclofenac 3%, and imiquimod 5% in treating high-risk basal cell carcinoma.

BACKGROUND: Some basal cell carcinoma (BCC) patients are considered as a high risk regarding the site, size, histopathological variant, or recurrence. High-risk BCC is a challenging therapeutic problem due to the trial to balance between complete surgical excision from one side and tissue preservation from the other side. AIM: To evaluate the efficacy of combining ablative CO2  laser, imiquimod 5%, and diclofenac 3% as a therapeutic regimen in high-risk and inoperable BCC. PATIENTS/METHODS: The study was conducted on 14 patients that were assessed clinically and pathologically then categorized regarding the site, size, histopathology, and fitness for surgery as high-risk inoperable BCC. They received an ablative session of CO2  laser, followed by application of diclofenac sodium 3% gel once daily for 5 days and imiquimod 5% cream for another 2 days. RESULTS: The study included 11 males and 3 females. Nine lesions were located on the scalp, 4 on the face, and one lesion on the trunk. All lesions were of large size >5 cm in diameter. Histopathology showed 4 patterns: nodular type in 8 patients, infiltrating type in 3 patients, metatypical type in 2 patients, and micronodular type in one patient. At the end of the treatment period, 9 patients showed significant (moderate to marked) improvement while 5 patients showed weak (poor to mild) response. Significant improvement was more observed in nodular type. Relapse was more observed during the 5th to 6th months with 2 patients showed no relapse. CONCLUSION: This combined regimen is a good alternative therapeutic modality in high-risk inoperable BCC especially the nodular pathologic pattern.

Comparison between 308-nm excimer light alone versus 308-nm excimer light and platelet-rich plasma in the treatment for localized vitiligo.

BACKGROUND: Monochromatic excimer light (MEL) is a safe and effective treatment for localized stable vitiligo. Previous reports of the combination of platelet-rich plasma (PRP) with narrowband ultraviolet B (NB-UVB) or excimer laser yielded conflicting results. AIMS: This prospective, self-controlled, randomized, comparative study aimed to assess whether the addition of PRP to MEL therapy would be of an additive benefit in the treatment for localized stable vitiligo. Patients/Methods The current study included 36 patients with at least 2 more or less symmetrical patches of localized stable vitiligo (72 patches). For each patient, each of the 2 vitiligo patches was randomly assigned to receive either MEL therapy (twice weekly) with bi-weekly intradermal PRP (group A) or MEL therapy alone (group B) for a maximum of 4 months or till complete repigmentation. The degree of repigmentation was categorized as absent (0%), poor (1-25%), moderate (26-50%), good (51-75%), or excellent (>75%). Patients were asked about their level of satisfaction (not satisfied at all, partially satisfied, satisfied, or completely satisfied). Side effects were recorded, and follow-up for 3 months was done. RESULTS: No statistically significant difference was observed between the 2 groups regarding the degree of repigmentation, the patients' level of satisfaction, and the frequency of side effects (p = 0.504, 0.490, and 0.912, respectively). At the end of the follow-up period, recurrence was observed in only 3 patients. CONCLUSIONS: The current study showed no statistically significant difference between using MEL alone or with intradermal PRP in the treatment for localized stable vitiligo.

Multifocal Cutaneous Granular Cell Tumor in Children: A Rare Entity.

ABSTRACT: Granular cell tumors (GCTs) are rare soft tissue tumors of Schwann cell origin that manifest as papulonodular lesions and occur mainly in adults. The diagnosis is usually confirmed by histopathology. Most of GCTs are benign, but some lesions may exhibit malignant criteria. This study is a retrospective case series including all children with histopathologically documented multiple GCTs who attended the dermatology department of the university hospitals between February 2008 and March 2021. The objective of our study was to raise awareness to this unrecognized and rare entity in such age group. The study included 9 patients (6 girls and 3 boys) with multiple GCTs. Their age ranged between 5 and 13 years. The lesions were skin-colored to light brown, firm, smooth-surfaced nodules. Most of the lesions were on the extremities, and their mean diameter was 160.5 mm2. None of the lesions exhibited any malignant criteria on histopathology. No extracutaneous or mucosal lesions were detected. Dermatologists should be aware of this rare condition in children because early recognition allows more conservative resection of the tumor and less invasive reconstruction of the defect. Our study highlights that multifocality does not necessarily indicate malignancy or other systemic comorbidities.

Autologous nanofat injection in treatment of scars: A clinico-histopathological study.

BACKGROUND: Scars are the unfortunate outcome of most injuries and some diseases. Its psychological impact on patients can deeply affect their quality of life. AIM: The aim of this study was to evaluate the efficacy of autologous nanofat injection in improving the aesthetic outcome of scars, combined with histopathological correlation of the response. PATIENTS AND METHODS: Thirty patients with scars of different etiologies undergone one session of nanofat injection and evaluation was done 6 months after the session. Efficacy of treatment was assessed clinically using Vancouver scar scale by two independent blinded dermatologists and histopathologically using image analysis system. RESULTS: The age of enrolled patients ranged from 18 to 40 years old. There was a statistically significant improvement on the total Vancouver scar scale regarding the height and pliability of the scars. Pathological evaluation showed an increase in epidermal thickness, increased number and density of collagen and elastic fibers along with neovascularization. CONCLUSION: Evidenced by clinical and pathological improvement, autologous nanofat injection is an effective strategy for treating scars of different etiologies.

Superficial Morphea: Clinicopathological Characteristics and a Novel Therapeutic Outcome to Excimer Light Therapy.

INTRODUCTION: Superficial morphea (SM) is an uncommon entity that was described in the literature without definitive correlation to localized scleroderma (LS) or other atrophoderma diseases. AIM: To demonstrate the clinicopathological features of SM and evaluate the efficacy of different therapeutic modalities in its management. PATIENTS AND METHODS: A total of 28 patients with SM were studied during the period from 2010 to 2015. Clinicopathological features and therapeutic outcomes were recorded and analyzed. RESULTS: Clinically, SM was predominant in females (71.4%) with an average onset at 33 years of age and an average duration of 15 months. It was commonly presented as asymptomatic, darkly pigmented, and multiple and slightly indurated patches. The lesions were mostly ill-defined, large-sized, and located more on the trunk. Histologically, thickening of collagen fibers was observed either localized to the papillary dermis only (38.9%) or extended into the upper reticular dermis (61.1%). Elastic fibers were generally diminished in the upper reticular dermis while the number of fibroblasts and basal melanin pigmentation were increased in the majority of cases (92.9% and 96.4%, respectively). The most commonly associated diseases were diabetes mellitus (50%) and hepatitis C virus (HCV) infection (42.8%), and their incidence was significantly higher than that in patients with LS. Excimer light showed promising effective results in the treatment of most cases (78.9%) while the response to other modalities such as topical corticosteroid alone or in combination with tacrolimus or treatment with UVA1 alone was less effective (7.1%, 23.1%, and 5%, respectively). CONCLUSION: Our results proposed that SM is a distinctive clinicopathological variant and not a stage in the spectrum of LS. The novel response of SM to excimer light and not for UVA1 therapy also suggests the different therapeutic outcome of SM from LS. Although SM has a significant association with DM and HCV infection, they seem not to affect the course of the disease.

Clinicopathologic, immunophenotyping and cytogenetic analysis of Sweet syndrome in Egyptian patients with acute myeloid leukemia.

BACKGROUND: Sweet syndrome (SS) is an uncommon dermatologic disorder that could be associated with hematologic malignancies. OBJECTIVE: To describe the clinicopathologic, immunophenotyping and cytogenetic characteristics of SS in Egyptian patients with acute myeloid leukemia (AML). METHODS: The study was conducted during the period from April 2011 to March 2015. For each patient, a clinical evaluation and histological assessment of cutaneous lesions were recorded. Diagnostic investigations, immunophenotyping and cytogenetic features of leukemia were analyzed. Therapeutic monitoring and follow up of both diseases were registered. RESULTS: The study included 13 patients (7 males and 6 females) with a mean age of 44.4±17.49years. Fever was recorded in 10 cases and most of the lesions (61.5%) appeared during the post remission period. Clinically, the lesions were more frequently located on the extremities (61.5%), presented as solitary lesion (53.8%) and mostly tender (69.2%). Atypical presentations were observed in 5 cases and included ulcerative lesion, indurated mass and a gangrenous mass. Histological assessment revealed two patterns of inflammatory reactions described as classic (dermal) form (38.5%) and deep (subcutaneous) form (61.5%). Laboratory investigations showed leukocytosis in 61.5%, neutropenia in 38.5%, anaemia in 92.3%, and thrombocytopenia in 84.6%. Bone marrow aspiration and biopsy showed suppressed trilineage hematopoesis in 84.6% and blast cell count >50% in 69.2%. The common subtypes of AML included M2 and M4 (23.1% for each). Cytogenetic studies revealed genetic abnormalities in 69.2% of cases. Most of the cases (76.9%) showed a poor response to oral prednisolone but responded well to alternative therapies, including dapsone, colchicine and cyclosporine. CONCLUSION: Sweet syndrome associated with AML may show atypical clinical forms that have an aggressive course and is mostly associated with subcutaneous involvement. Although chemotherapy of AML may play a significant role in the development of SS, the exact mechanism remains unclear. The disease is considered a steroid refractory and genetic abnormalities may have a role in altering the classic nature of the disease.

Cutaneous Granulomas Associated With Interferon Therapy.

Treatment with interferon (IFN) could be associated with variable cutaneous adverse reactions. The aim of this study was to describe the clinicopathological spectrum of cutaneous granulomas associated with IFN therapy and identify the causal relation between IFN therapy and granulomatous reactions. The study included 18 patients (16 males and 2 females) with an average age of 48 years. Clinically, most of the lesions were solitary (83.3%) and located on the face (44.4%) and/or trunk (38.9%). The lesions were commonly presented as nodules (33.3%) or plaques (27.8%) with a common size of 5-10 cm. Granulomatous reactions were localized to the injection site in 4 cases, distributed on other body areas (remote granuloma) in 11 cases, and associated with lung involvement (systemic granuloma) in 3 cases. Histologically, injection site granuloma showed suppurative reaction in 75% and sarcoidal reaction in 25%. Remote granuloma showed tuberculoid reaction in 27.3%, interstitial in 27.3%, and sarcoidal in 45.4%. Systemic granuloma showed sarcoidal reaction in all cases. After withdrawal of IFN, only 3 lesions showed spontaneous complete clearance, whereas most of the lesions (83.3%) showed only partial improvement. Our results suggested that IFN is not a causal agent of all associated cutaneous granulomas but it mostly provokes the appearance of granulomatous reactions in susceptible individuals. Findings that prove this concept include the formation of granuloma in body sites away from the injection site, the heterogeneous pattern of granuloma both clinically and histologically, and incomplete clearance of most of the lesions after withdrawal of IFN.

Dermal filler complications: a clinicopathologic study with a spectrum of histologic reaction patterns.

Although dermal fillers are generally accepted as safe and well-tolerable cosmetic tools, adverse reaction still forms a prognostic problem. The aim of this study was to demonstrate the clinicopathologic patterns of dermal filler complications in our center. A 5-year single-center study that included patients complained from filler complications and referred to the dermatopathology unit in Al-Azhar University for histologic assessment. The study included 38 female patients with an average age of 47 years. The mean onset of complications was 14.6 ± 5.27 months after injection. The injected material included hyaluronic acid (18.4%), silicone (52.6%), bovine collagen (15.8%) and polyacrylamide hydrogel (13.2%). Most lesions were located on the face (55.3%), less commonly on the hands (18.4%), buttocks (21%), and rarely on the vulva (5.3%). The clinical spectrum included indurated plaque (23.7%), nodular lesion (31.6%), inflammatory mass (15.8%), atrophic lesion (10.5%), skin discoloration (13.1%) and ulceration (5.3%). Histologically, granulomatous reaction was the major finding, either a foreign body granuloma (34.2%) or infectious granuloma (13.2%). Other histologic reactions included dermal pseudocysts with chronic inflammation (26.3%), dermal fibrosis (15.8%), and eosinophilic panniculitis (10.5%). Our results confirmed that dermal fillers could be manifested with variable clinical presentations and show different histologic reactions. Because of long-standing duration until complications occur, history taking is crucial and should be emphasized in every suspected patient. It is hoped that this article will increase awareness for recognition of these variable complications and help select the appropriate therapy.

Pseudoperforation: an uncommon histologic phenomenon in prurigo misleading for the diagnosis of reactive perforating collagenosis.

Prurigo is a common skin condition characterized by vigorous scratching. Although ulceration is not uncommon in prurigo, a perforating-like lesion was not previously reported. In this study we described series of cases of prurigo with perforating-like lesions and discussed its relation to acquired perforating dermatoses. The study included 32 cases, during the period from 2008 to 2013. Clinical data and histological features were recorded and analyzed. The study included 78.1% males and 21.9% females with a mean age of 39.3 ± 5.61 years. History of insect bite was evident in 28.1%, hepatitis C virus infection in 46.9%, and diabetes mellitus in 9.4% of patients. Histologically, well developed lesions showed full thickness epidermal degeneration overlay by a cup-shaped crater. The contents of the crater included collagen and elastic fibers, bacterial colonies, inflammatory cells and necrotic keratin. The dermis showed non-altered collagen, increased vascularity and mixed inflammatory infiltrate. We believe that this pseudoperforation process is a secondary response to vigorous scratching in prurigo patients and not a primary mechanism as occurred in perforating dermatoses. The absence of altered collagen, the presence of full thickness epidermal necrosis and concomitant elimination of elastic fibers are significant histologic clues for differentiation between both conditions.

The spectrum of cutaneous infection in diabetic patients with hepatitis C virus infection: a single-center study from egypt.

CONTEXT: Hepatitis-C virus (HCV) infection and diabetes mellitus (DM) have a significant association with skin disorders. AIMS: The aim of this study was to assess the impact of HCV infection on the pattern of cutaneous infections among diabetic patients. METHODS AND MATERIAL: A prospective study included diabetic patients who attended Al-Hussein University hospital, Cairo during the period from 2008 to 2010. Patients were examined for skin infections, and investigated for HCV infection. STATISTICAL ANALYSIS USED: SPSS (version 11.5). RESULTS: The study included 163 patients (102 males and 61 females) with a mean age of 46.2 ± 4.83 years. Ninety five patients (58.3%) were HCV+ve (group A) while 68 patients (41.8%) were HCV-ve (group B). Skin infections in group A included fungal (48.4%), viral (26.3%), bacterial (22.1%) and parasitic (3.2%) while in group B, the spectrum included bacterial (41.2%), fungal (39.7%), viral (11.7%) and parasitic (7.4%). Onychomycosis was the commonest infection in group A (25.2%) compared with folliculitis in group B (19.1%). Cutaneous infections in HCV+ patients were more characterized by increased severity, aggressive course, resistance to treatment and rapid relapse. CONCLUSIONS: HCV infection has a significant impact in increasing and changing the spectrum of skin infections in diabetic patients. Severe and resistant infections in diabetics could be an important sign of HCV infection.

Acquired melanocytic nevi in Egyptian patients: a clinicopathological study.

INTRODUCTION: Melanocytic nevi (MN) are the most important simulants of melanoma. Although acquired nevi are usually clinically stable, they may show abnormal clinical behavior. This study assessed the histological changes and prognosis of acquired MN with changing clinical behavior in Egyptian patients. METHODS: The study included 236 patients that were classified into two groups; Group A included nevi with abnormal clinical presentation and Group B included clinically typical nevi. RESULTS: Each group included 118 patients with a predominance of female patients. Abnormal clinical presentation in Group A included altered pigmentation (35.6%), rapid enlargement (30.5%), keratotic changes (16.9%), inflammation (7.6%), ulceration (5.1%), and hemorrhage (4.2%). Typical histological features were significantly higher (p = 0.008) in Group B (99.2%) compared with Group A (87.3%). Atypical histological features were significantly higher (p = 0.002) in Group A, with higher numbers of ulcerative and altered pigmented nevi. Malignant changes showed no significant difference (p = 0.47) between the two groups. No relapse was recorded after excision of any lesion. DISCUSSION: Among Egyptians, changing clinical behavior of MN may show histological atypia but low risk of malignant transformation. Early excision and follow-up of ulcerative and altered pigmented nevi are recommended.

Atypical mycobacterial cutaneous infections in Egyptians: a clinicopathological study.

Atypical mycobacteria comprise an uncommon heterogenous non-tuberculous group of acid-fast bacteria that rarely involve skin. The pattern of atypical mycobacterial cutaneous infections (AMCI) has not been previously studied in Egypt. The aim of this study was to describe the clinical characteristics, pathological features and species profile of AMCI among Egyptian patients. A retrospective study included 46 cases, diagnosed with AMCI during the period 2002 to 2012. The study included 34 males (73.9%) and 12 females (26.9%). The average age of patients was 39 years while the average duration of lesions was 15 months. The lesions were mostly located on the extremities (91.3%) and there was predominance of single (65.2%) and nodular (41.4%) lesions. History of trauma was confirmed in 91.3%. Histologically, the granulomas were mostly superficial (67.4%) with predominance of nodular suppurative pattern (84.8%). Other significant histological findings included epidermal hypertrophy (100%), presence of large-sized multinucleated giant cells (87%) and intrafollicular neutrophilic abscesses (84.8%). The diagnosis was proved by direct smear in 6.5%, skin biopsy in 10.9%, tissue culture in 47.8% and polymerase chain reaction (PCR) in 34.8%. Isolated species included Mycobacterium marinum (84.8%), Mycobacterium fortuitum (10.9%) and Mycobacterium kansasii (4.3%). Although the results of this study recommend that the diagnosis of AMCI is based mainly on culture and PCR, other clinicopathological features such as history of trauma, acral location of the lesion and suppurative granulomatous reaction with intrafollicular abscesses could be helpful clues in suspecting AMCI.

Pulsed dye laser versus Nd:YAG laser in the treatment of plantar warts: a comparative study.

Plantar warts are common viral infection that are usually challenging in treatment. Conventional treatment methods are usually invasive, have low efficacy, and need long recovery periods. In this study, we compared pulsed dye laser (PDL) and neodymium yttrium aluminum garnet (Nd:YAG) lasers in the treatment of recalcitrant plantar warts. The study included 46 patients with multiple plantar warts. In each patient, lesions were divided into two groups: one treated with Nd:YAG (spot size, 7 mm; energy, 100 J/cm(2); and pulse duration, 20 ms) and the other with PDL (spot size, 7 mm; energy, 8 J/cm(2); and pulse duration, 0.5 ms). Laser sessions were applied every 2 weeks with maximum of six sessions. The study included 63% males and 37% females with a mean age of 29.6 ± 7.34 years. The cure rate was 73.9% with PDL with no significant difference (p = 0.87) from Nd:YAG (78.3%). The number of sessions required was more in PDL (mean, 5.05 ± 0.2) compared with Nd:YAG (mean, 4.65 ± 0.5) but without significant difference. Complications were significantly higher with Nd:YAG (43.5%) compared with PDL (8.7%). Hematoma was the most common complication recorded by Nd:YAG (28.3 %), and it was significantly higher (p = 0.002) than PDL (2.2%). Relapse was recorded in 8.7% with Nd:YAG compared with 13% in PDL with no significant difference (p = 0.74). Our results suggested that PDL and Nd:YAG lasers are effective in the treatment of resistant plantar warts. PDL is safer and less painful but needs more sessions, while Nd:YAG is more painful and shows more complications.

A multicenter clinicomycological study evaluating the spectrum of adult tinea capitis in Egypt.

INTRODUCTION: Tinea capitis (TC) is a common fungal infection in children but is less frequently encountered in adults. This study evaluates the clinical characteristics and mycological studies of adult TC among the Egyptian population. METHODS: A multicenter study included patients diagnosed with TC from 2002 to 2012. RESULTS: The study included 58 patients with a predominance of females (84.5%). The average age was 43.2 years and the mean duration of lesions was 7.1 ± 2.41 months. A history of close contact with animals was reported in 17.2% and Hepatitis C virus infection was recorded in 34.4%. Clinically, scaly scalp (37.9%), alopecia (22.4%), and pyoderma-like lesions (13.8%) were the most common presentations. The parietal (27.6%) and temporal (25.8%) regions were the most affected areas. KOH mounting showed endothrix spores in 56.9%, ectothrix spores in 34.5%, and favic chaplets (hyphae) in 8.6%. Fungal culture showed Trichophyton violaceum in 56.9%, Microsporum audouinii in 19%, Microsporum canis in 15.5%, and Trichophyton schoenleini in 8.6%. CONCLUSIONS: Trichophyton violaceum is the most common cause of adult TC among Egyptians. Increased awareness of variable clinical forms of TC will help in identifying more cases, especially those with HCV infection and close contact with animals.

Hypopigmented mycosis fungoides in Egyptian patients.

Hypopigmented mycosis fungoides (HMF) is uncommon clinical variant that was commonly observed in dark-skinned individuals. We described the clinical characteristics, pathological features, immunohistochemical profile and prognosis of HMF in Egyptian patients. During the period from January 2004 to December 2011, we were able to diagnose and follow up 27 patients with HMF. The study included 18 males (66.7%) and 9 females (33.3%) with a mean age of 35.39 ±13.13 years. The duration ranged from 1 to 6 years with a mean of 3.26 ±1.7 years. The majority of patients were skin type IV (63%) and presented with multiple (88.9%), asymptomatic (74.1%), ill-defined (70.4%) and non-scaly (77.8%) lesions distributed on the trunk (81.5%). Histologically, epidermotropic lymphocytes were observed in 100%, basal alignment of lymphocytes in 81.5%, Pautrier's microabscesses in 29% and folliculotropism in 18.5%. Immunostaining showed predominance of epidermal CD8+ cells in 51.9% while in 29.6% CD4+ cells were predominant. Phototherapy was effective in 86.7% of patients with success rate 66.7% of narrow band (NB) ultraviolet-B and 80% of psoralen ultraviolet-A. HMF among Egyptians could be classified as non-aggressive epidermotropic cytotoxic CD8+ variant. It is common among middle age males with skin type IV and mostly well respond to phototherapy.
